I'm using stock cooler and currently am at 3.9GHz. Not gonna push further as prime95 has high temps(80+ on small FFTs) after 4.0GHz. Would it give me noticeable extra performance in games? Will be also getting 7870 tahiti le.
My mates 2500k will demoloish every game on the market at stock clocks, so the answer is no. I can foresee the new x86 chipped consoles helping to push game resources up somewhat, but given the power restrictions of those processors it is unlikely there will be any games that a recent intel quad wont be able to handle at stock.
