Yeah that is nice site. I have been messing for regeisty for years. It doesn't really give huge perfomance boost. The most benfit I got was 5% gain and that took about 2 hrs to tweak. If you want faster machine you most overclock. If you do overclock do it slowly. And test test test. Right now out of my old amd 1800xp got extra 500 mhz out of. If you going to overclcok make sure have I good heat sink and other fans to keep her cool. If raise the voltage your machine will ran hotter and heat is the enemy.

I agree. I'm not big on overclocking in general. If you push too hard you'll start having real issues and you stand a good chance that you'll fry something. It'* like trying to get 300hp out of a Neon...
