Today we are going to provide you with a basic step-by-step guide on how to overclock a graphics card. The GeForce 8600 GT is the test subject and while we do not feel this graphics card is the best gaming solution at its standard clock frequencies, with a little overclocking it can deliver respectful performance. In order to achieve respectful performance the GPU (Graphics Processing Unit) must be bumped up by nearly 30%, while the memory will take a 30% frequency injection.
As you are now aware, overclocking your graphics card can be a quick and easy way to squeeze a bit more performance out of your system without having to spend any more money. In this case we were able to push the GeForce 8600 GT, which costs around $135 US, to rival the more expensive GeForce 8600 GTS graphics cards, which cost roughly $190 US. The advantage to doing this with an 8600 GT graphics card is that it can be powered for a basic 300-400w power supply and there are no additional PCI Express power cables required.
