Sorry if these questions are really nooby questions, I only recently decided to switch from ATI/AMD to NVIDIA.
you CAN run physx off of one card but the whole point of it is to split the load up better between the two cards and pull stress off of your CPU. If you run it off a single card, your CPU does less but then your GPU does more so it's not really worth it with a single card.
before someone yells at me for incorrect info, i am definately not a physx pro. This is just stuff that i learned from own experiences testing physx.
honestly though, physx isn't where it could be imo. i saw a 2-3 fps difference while using but then again that mite not of even been because of the physx(only tried it a few times).
i was using a gtx275 for main, gts250 for physx. i ended up just buying another gtx275 and runnin sli...much better performance for the games i was playing.Edited by Hazzeedayz - 7/19/11 at 8:57am
