For you guys who own Nvidia Graphics on PC or Laptop
EVGA Precision is a great Overclocking utility.
I don't really overclock my Nvidia 9100M G as it is a bad idea to overclock lousy GPUs.
You may end up destroying it over a measly few frames per second.
This tool's friendly interface doesn't need introduction.
Word of Warning:
Do not happily push the bars and press apply without thinking,especially the memory clock bar.
I am not responsible for the destruction of your GFX.
