VisionTek ATI Radeon HD 2400 Pro 512MB isn't bad

I found this graphics card " ATI Radeon HD 2400 Pro 512MB ( AGP 8X )" on bestbuy site and noticed that  many of people have troubles with this card and give it a low ranking , but I decided to buy and test it. It's really a good card and it's too easy to install it and make it work. It gives a high performance and sharp images and can run nearly all games. You can download the driver for this card from the VisionTek web site and it will work easily. I know that it isn't the best graphics card but it will work well. Its core speed is 525Mhz and it has a 512MB DDR2 800Mhz memory and support DirectX 10 and it can be overclock but on your responsibility.It can work with two monitors and has a TV-out port and support ATI Avivo technology.  

The most poweful processor in the world now

No one can deny that Intel Core i7 Extreme Edition is the most powerful processor in the world now. It's the fastest processor on the planet as its core speed is 3.2 Ghz without overclocking and it has four cores and each one can  make two threads and that make the processor work like it has 8 cores. It's really wonderful , it has 8 Mb of Intel smart cache and 3 Channels of DDR3 1066 MHz memory the will make your PC launch as a rocket! It's mainly designed for ultimate gaming and graphics designing, so many of use really don't need to it as  it's very expensive, it will cost you about 1100$ for the processor only.Can you imagine how much  the complete pc will cost you?

the largest HD TV in the world

Panasonic 150 inch PDP is the largest HDTV in the world. Can you imagine playing a video game on this TV? I think the characters of the game will be as tall as you. It will be wonderful experience to play need for speed undercover on this TV. The only thing that will prevent you from doing so is its price. It may cost you from 100000$ to 150000$. I want to know really who can buy it ?!

AMD or Intel ?

In the field of producing processors, all the manufacturers are disappeared or will do soon ,but Intel and AMD are the only survivors. Most of computer users ask which is the best. No doubt that Intel is no.1 in producing the most powerful processors but AMD processors are also powerful. Inter processors introduce higher processing speed for games and multitasking applications but there are many disadvantages:
- It gives out great heat and that raise the temperature of the processor and decrease its life, and you may need to buy cooling systems which are expensive.
-Intel's processors are very expensive specially the new ones.
-Intel depends on the core speed only and doesn't provide special technologies ( Hyper threading is the only one)

AMD is doing well to introduce unique technologies to enhance performance and to build smart processors. It cares about the power efficiency and its processors are designed to reduce the power needed for operating. It was the first company to build a 64-bit processor and it was the first manufacturer of the multicore processors. Also the prices of the processors are reasonable. You can see this processor to know about AMD technologies. I personally prefer AMD.

Nu SuperMulti Drive , very beautiful external DVD drive but not the best

Some of us need to buy an external DVD drive, but they should search for a beautiful and speedy one. I found this DVD drive that looks like a thing from the space! It's Nu SuperMulti Drive ESW846B .It's really beautiful ,but unfortunately it can't introduce the best performance.It connect to your PC or laptop through a USB cable and use only 7% (maximum) form your processor performance. The only disadvantage of this drive is its reading and writing speed, as it's slower than many other DVD drives but for a standard user, it's a good choice. It also support the LightScribe technology and it doesn't take big roam on your desk as it's thin.
In tests, it took 14min and 20sec to wirte 4.38 GB on a standard DVD R at 8X, and it took 11min and 3.6sec to copy them from the DVD.

NVIDIA GeForce 8800 vs GeForce9600, which one will win!

Some of us have a trouble when buying a new graphics card from nvidia ,which one they should buy 8800GT , 8800GTS ,8800GTX or 9600GT!
In fact , GeForce 8800GTS (512MB only) is the most powerful graphics card in them. It has the fastest GPU and shader clock and it's really fast. It's slightly better than 8800GTX ,but not better than 8800 Ultra.The only difference between 8800GTS and the 8800GTX is that 8800GTX has a 384-Bit memory interface that makes the data transfer  faster but its GPU is slower.
I can arrange these cards from the strongest to the weakest:

1. GeForce 8800GTS (512MB only)
2. GeForce 8800GTX
3. GeForce 9600GT
4. GeForce 8800GT

Get the most powerful ATI GPU HD 4870 with MSI R4870X2

MSI R4870X2  is of the most powerful graphics cards in the world and it's the most powerful MSI graphics card. It contain the latest ATI HD 4870 GPU that can deliver unexpected performance with the most new games and you will see the real power of games. This card has the most new DDR5 ram with 2 GB. It works with RV770 GPU that can work under direct X 10.1 to intoduce unbeleivable graphics. This card consistes of two ATI Radeon HD 4870 GPUs to performe a very fast performance in Direct X 10.1 games and the two GPUs makes a total 1600 processing streams. It has all what you will need from a graphics card and it has a good cooling system but it isn't very good really and I think that MSI MUST work on this problem very quickly.But, the result of testing this card without changing any settings or overclocking it ,was fantastic. It score 13320 points in 3DMark06 and this result may increase if a powerful computer is used.Also, its price is good and cheaper than some weaker cards from NVIDIA .
Ranking: 4.5/5

How to overclock your NVIDIA graphics card

Some of NVIDIA graphics cards can be overclocked to increase it speed and to get a higher performance level. I found a program called " EVGA Precision 1.3.2 " that can overclock nvidia graphics cards and monitor the temprature of it. You can download it here. But note that this will work for GeForce 6,7,8,9 and 280 GTX series only and overclocking increases the GPU temperature and sometimes destroy the hardware so you it on your resposibiltiy and I recommend using a very efficient cooling system before overclocking any hardware.

NVIDIA 280 GTX :powerful performance with some problems

Every one has heard about the power of the new nvidia graphics card - NVIDIA 280 GTX - which is the most expensive graphics card now. Yes, this is a very poweful card which contains 1.4 billion transistors and includes the nvidia PhysX and CUDA technologies, but it's really hard to use it. First, its price is very high and it gives out great heat and you shouldn't buy it if yiu haven't a very efficient cooling system and a big chassis for your computer and a water cooling system is recommended specially to overclock its speed and all that will cost too much in addition to its price. Also you need to use a very powerful processor with high speed and it's recommended to be 3.2Ghz for dual core processor and 3.0Ghz for a quad core one. This card delivers a very high performance but notice that it isn't the fastest one as NVIDIA 9800GTX is faster but 280GTX has more processing streams.But after all that I can say that the best things in this card is the nvidia PhysX and CUDA technologies,the overclocking ability and the high number of shader cores ,but there are big problems you must face if you buy this card.First its high price ,second the very high temperture ( can reach 80'C) ,third it doesn't support direct X 10.1 at all and it doesn't have a DDR5 ram. I see that ATI graphics cards can deliver high performance without these problems.

What will you do if Quick Time asks for a CD to run a normal video file ?

In some cases when you try to open a multimedia file with Quick Time player,it asks you to put a CD into the CD drive to open that file although it is on the hard disk. The quick solution to this problem is to put any CD into the CD Drive, but the real reason for this problem is that you have added a file that was on a CD or DVD  to the favorites menu and for an unknown reason ,the program must check if this file is exist on the CD before opening the file you want open at that moment.

Seagate FreeAgent XTreme 1.5TB on the top of external hard disks

Seagate introduces the best external hard disk for 2008 and it's really amazing and you can called it "all in one". It has all what you need in an external hard disk ,the large capacity ,the smart appearance ,the flexibility that allows you to lay the HD on its side or stand it upright and the long warranty. You can also connect it to your computer by 3 ways ( USB 2.0 480MB/s ,Firewire 400 or eSATA 3GB/s) to maximize the speed of data transfer according to you computer. It has 32MB of cache to increase processing speed and its speed is 7200 rpm for best performance as the higher speeds always make the HD temperature high and this badly affect the lifetime of the device, so 7200rpm is the best speed now. I recommend this product to you , but note that ALL external hard drives may have problems with windows vista 64bit when connecting the device with eSATA and this hard may not work properly with eSATA on vista 64Bit and Western Digital hard drive also do so.
Ranking for this HD: 5/5

How to compress 1 GB to 10 MB

If you have big file or folder which consumes large space of you HDD and you want to upload it to any server ,you will need to use a powerful compression program to decrease its size and I found a perfect one. KGB Archiver can compress file to 15% or less of its original size. It is really wonderful but to do the best compression you should have a large RAMs ,but it can also work with many modes so as to work with little memory. You should try this program and save you disk space.

Corsair Dominator Twin3x2048 -1800C7DFIN just a normal DDR3 RAM

This is one of the first DDR3 RAMs found in markets and it is really good but won't meet your expectations if you think it will deliver incredible performance. It has the overclocking feature, but trust me, some of DDR2 RAMs can deliver a better performance. I know that its freq. is 1800Mhz but its real performance is normal and moreover its price is very high ( about 425$). It achieved 5430MB/s in memory bandwidth test in SiSoft Sandra and some DDR2 RAMs can achieve higher results. So I advice you not to buy this RAMs if you want a very powerful performance for games and other application.

Panasonic DMR-BW500 isn't a normal Blu-ray recorder

The worst graphics card I have ever seen

I used deffirent kinds of graphics cards but I found that the worst video cards are always the Intel's ones. These cards are slower than the NVIDIA and ATI cards and they cause many troubles with games and also slow your computer. I tried the AGP cards and also the PCIe cards and found that the Intel graphics cards give bad images in games and the they deliver only 60-70% of the ATI graphics cards performance. Intel used to put its graphics cards on its chipset to force the user to use them but now Intel introduced new chipsets without its graphics cards but at high cost. I advise you NOT to use the Intel's graphics cards as they cause high temperature inside your PC and you will find that the motherboard temperature will reach over 45'C while playing games and you will notice that games run slower  than they should. So, the best solution is to use the ATI or NVIDIA graphics cards and disable the Intel one in your PC if it is on your motherboard.

It has a beautiful big screen (3.2") that will make you happy when you watch your videos and TV shows that you can buy also from Zune marketplace. It is raelly wonderful device with touch controls and beautiful design. I advise you to get it.

Google Chrome : High speed with big trick!

Everyone now must have heard about the powers of the new Google's browser "Chrome" and its high speed in browsing the web specially the feature of multitabbing. All that are really very good and indeed it is better than Microsoft internet explorer and also faster than Firefox ,but it has a big problem. This problem isn't inside the program itself ,but it is in what google do with its browser.The Federal Office for Information Security in Germany has warned  German people from using Google Chrome as it allows Google to reach to the personal informatoin of its users and that is what Google said in the item No.1 of Google Chrome privacy policy which give Google all rights to get to your content and publishing it. So, I advise you not to use this browser and Firefox will give you what you want: the speed and the security.

UHARC v3.06 a very powerful compression program

I tried many programs to see what the best compression program is ,but I found that WinRar isn't the best one. If you try UHARC ,you will find that it has the best compression ratio specially for files and huge games and  its compression of the multimedia files is better than any other program but not very good like other types of files. One of may friends tried to compress a 4 GB game with it and compressed it to 650MB!
You should try this program and it is also a freeware. Download it here.

Toshiba laptops are with Norton now

Toshiba has signed a contract with Symantec to provide Toshiba laptops with Norton 360 and Norton Internet Security 2009. The users can use these programs for 60 days for free and after this period, they should pay for them. Symantec will provide its antivirus program with three languages (English,French and Spanish). This contract is only an advertisement for Symantec products and I think they chose Toshiba for this deal as its laptops are expensive and its customers can easily pay for the Symantec antivirus programs. But in my opinion it's a bad thing from Toshiba to agree to this deal because it may cause problems for customers who don't want to use Norton as their internet security suite as it slows their computers and uninstalling it is very difficult.

How to choose a perfect graphics card

First, you should decide on what will you do with your graphics card
so as not to waste your money.For business, a graphics card like ATI
Radeon HD 4870 is a loss!
Now,I'll illustrate how to get the best graphics card for gaming.There
are some things you should care about.
1.The GPU speed:
GPU is a processor designed for graphic,so the
speed is important to make your games run smoothly.So, it's advisable
to get a card with 550Mhz or faster core clock. Be careful, the core clock may be misleading as there are more important factors that should be considered, the some of  them is the shader clock for nVidia cards and processing streams for ATI ones. You may  buy a card with 1200 Mhz or
faster shader clock(for nVidia cards only) or 800 or more processing streams for ATI cards.
2.Memory:
 For running games faster,the graphics card should have 512 MB memory
at least.Also, the memory interface is important and should be 256bit or
more.The video RAM is important for better shared quality and details for most new games.
3.The doubled performance:
Now you can get a doubled performance with two ways.
The first is to put two graphic cards or more on the motherboard
to work together. This technology is called Crossfire X for ATI and
SLI for NVIDIA.
The second is to buy a dual core graphic card.You will find "X2"
in the end of the name of dual core graphic cards.
Here,before using any of them you should take a great care of your power supply and make sure that it can run these cards or you will have to buy a new one.
4.Other technologies:
The graphic card must support the following:
-Model shader 4.1 or later.
-PCIe 2.0
-Direct X10.1 or later.
-OpenGL 3 or later.

5.How to understand the code name of graphics cards:
nVidia and ATI use a number (code) for their products.
for each series of graphics cards you may notice the name of it (like ATI HD 4770) contains for numbers.
the the first one (from left) is the series number and the more important is the second  one.
for cards coded  x4xx  deliver the essential performance like playing hd movies and a few old games.
for cards coded   x6xx  are the very good for users who want to play games at midum  settings and note paying very much.
for cards coded  x8xx is the most powerful and could deliver high performance for most new and upcoming games.

500 gigabytes on a blu-ray disk!

Can you imagine that one blu-ray disk can replace your hard disk drive!
Pioneer will produce soon a blu-ray disk that can store up to 500 GB of data.
It consists of 20 layers and that makes it possible to store such huge amount of data on one disk,but it isn't an easy process as they must be sure that the information written on any layer, doesn't overlaps with
the information on the other layers.I think when this disk is released,
it will make great changes in all storage devices and in the world of entertainment.

If you are a facebook user,you will be a target for a new virus.It seems to be a Trojan and
your computer will be infected when you open a link in a message which looks like a message

open it,a picture of a clown appears and the virus infect your computer immediately.
So be careful ,the viruses also spread through many other social sites.

Don't play with Firefox 3 !

The latest Firefox 3 isn't compatible with many adds-on that work with the

older versions of Firefox.So, many websites give a way to change the 

browser settings to make the old adds-on work in Firefox 3.This is a 

dangerous process that makes the browser unsafe and opens security ports.

Also, after changing some settings and install the old adds-on, Firefox 3 may

not work and not be able to connect to the internet ,so please wait until the complete version of Firefox 3 is available in the end of this year

and don't play with Firefox 3!

64bit processors ,what does that mean?

64bit processors are the most powerful processors, it can do many process

faster than 32bit processors like running a game,playing music,downloading

 something from the internet and more all in the same time,but not at the speed

of  64bit multi-core processors.

AMD was the first company to use the 64bit structure in its processors under the

name "Athelon 64".

64bit structure has a doubled bandwidth of 32bit structure,so it can do more.

But notice that:

1.64bit processors need a compatible motherboards.Not any motherboard will

   work with these processors.

2.64bit processors give out great heat,so make sure that you have an efficient

   cooling solution.

3.To enjoy the features of the 64bit processors,you must install windows xp 64bit 

  or windows vista 64bit, otherwise,all 64bit features will not be used.

3 very rare icons most of users don't know

Here I'll provide you with two useful shortcut icons to put them on your
desktop to make you do two things faster.

How to prevent losing your data and information caused by your computer!

Not only viruses and spyware can cause data losing
,but also your window does that.
To make the applications work faster, windows uses
a new technology called "Write behind caching" and that means
if a program wants to write data no the hard disk
,windows tells the application that the data have already been written on the disk
,but actually they haven't.
Windows waits a suitable time to write data on the HD.
What will happen if any problem occurs
within this time like a technical problem or the power is cut off?
Easily all unsaved data will be lost.

For more security ,you can disable this function :
1. From start menu open "Run".
2. Type "Regedit" then press open.
3. When the "Registry editor"window opens ,click on "HKEY_LOCAL_MACHINE",
then open system > CurrentControlSet > control >File System.
4. If this feature is being used on your computer,you will find "Write behind caching"
on the right "Write behind caching".make the mouse pointer on it
then press the right button.
5. Click "Modify" then make all numbers in it equal "0"zero ,all that to disable this
feature then press"OK".
