The *real* benchmarks, in my opinion, will involve a variety of games (Crysis, Metro2033, BF2, etc.) at 1280x1024 , 1920x1080, 2560x1600 ,etc., and pit FX4130 quadcore vs. i5/2500k quadcore under Win7 when both systems are tested using:
GTX580
6970
GTX580 SLI
6970 CF
I think most folks are going to be disappointed with FX81XX performance in gaming with Win7. (If 4 cores can easily be disabled in BIOS and/or within Win7 to reduce overhead for gaming, that might help...)
