I have a qx 6800 cpu so same as yours but higher stock clock and free multi.
I just overclocked mine to 3.6 so still under your clock of 3.7 and i scored
14572 3dmark score
15597 gpu score
12173 cpu score
I get 14574 on windows 7 64bit ultimate with:
GTX280 and my i7 920 @ 3.6Gig
Seems a bit slow, my GPU score was 17064 with a Vantage score of 18713.
i7 4.1 Ghz 8 threads v Q6600 3.7 Ghz 4 threads in a CPU loving benchmark, there is only going to be one winner.
