I have a Q6600 @ 3.4Ghz and paired it with a cheap 5870. I'm still able to play most games at high settings, even at 2560X1600. IMO it is one of the 'best' CPU's ever made. Will be somewhat sad to upgrade when IvyBridge-E is released.
I would have liked to have seen the same benchmarks with the processor overclocked too but nice article. Q6600 FTW!
