does PhysX use all cards in SLI?
If I have a 2/3/4way SLI system, are all of the shaders summed together and used for PhysX or does the load fall onto one card, or is it sent unequally (lesser graphically loaded cards), or what exactly? I'm curious whether dedicated PhysX has any point on SLI systems since sometimes dedicated cards can be slower it seems.

PhysX only runs on 1 GPU. It has no ability to split the load over multiple GPUs.
