Just got my 2 nvidia 460 1gb evga cards. games are running really well, crysis, metro, gt4 , fallout nv and others are running great. Crysis and metro are so much smoother now i can hardly belive it. Question i have is about physx. I have 1 game mafia 2 and for some reason setting the physx to cpu instead on one of the gpu,s seems to give me a better performance of that game. Is that the case for everyone? will i get a better physx performance using the cpu and not the gpu's?
 
You will get best (smoothest) performance in Mafia II w/ PhysX by not using SLI and dedicating one GPU to rendering and the other to PhysX. Using CPU PhysX option means Mafia II will disable most of the advanced PhysX effects which is why it seems smoother.
 
ahh ok rroff thats great advice, thanks mate ill try that. other games run fantastic even metro. so was a little stumped why mafia 2 wasnt that smooth.
