I have a XFX 6600GT 128MB AGP on my other PC and I was going to OC it because I really don't care if it dies. I was wondering what I would need to OC to to see any results and what comparible card would it upgrade to? Also if I use a aftermarket cooler would the -20c actually help in the long run? I'm using DDR2 Corsair Value RAM and I'm not that familiar with OC'ing older cards.
