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

Get the most clear and full HD video with Sony HDR-CX12 digital camera

You can capture wonderful videos with Sony HDR-CX12 digital camera which includes many new technologies like Face Detection and Smile Shutter which enable you you to take pictures among a group of smiles without switching to the stable image mode. It can record high HD videos (1080X1920) at 10.2 Mega pixel on the flash memory Sony Memory Stick Pro Duo. But the special thing you will notice when using this camera, is that children can use it very easily and it doesn't need a professional user. 

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.
