How do you use a dedicated PhysX card?
I have a GTX 470 SLI setup, and I'm thinking of getting a GTX 580 and use one of the GTX 470s for PhysX. I would put the other GTX 470 in another system. I know I can't SLI a GTX 580 and 470, but how would I use the GTX 470 for Physx? Would I just put it in the extra slot where the GTX 470 was?
