I can't get my q6600 past 2.7 stable. I got it to 2.8 but it ran WAY hotter then I wanted. Even on 2.7 though its a good bit faster, so I'm happy. I've also got the OCZ SLI mem, good stuff there. Although I'm running a 8800gt though. I've got a 2nd on the way though, but since alot of games aren't that super in SLI yet, no hurry to get the 2nd in.
