Hey guys, I just recently bought an Open box GTX 480...$140 and it was BRAND NEW yay me. Now In wow I have encountered my CPU is heavily bottlenecking my gpu in WOW. I just ordered a new Heatsink...Will i be able to over clock my CPU to get the full potential of my GTX 480 cause I know the thing is a monster.. Or am I better off buying a FX-4120 for cheap? Thanks!
