Right click desktop, properties then settings than advanced than the tab with your video card and you should see overclocking settings. It requires a reboot but should be very easy.

I wouldn't overclock it that much if I were you. The 6600GT runs rather hot. Unless you have a decent GPU cooler, I wouldn't overclock it. Besides, the 6600GT should be able to run any game pretty well.
