The results vary on every website it seems, it's hard to guess which one to believe or whether the performance varies by large amounts on each CPU.
Overclock 3D Game performance
Tomshardware Crysis
Tomshardware Dirt 2
It's definitely a lot of mixed results, and it's hard to believe some of the results from Overclock3D, in my opinion it would be better priced at $250 and $160 rather than $300 and $200.
