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.
