You can. There's nothing that prevents you from. They're detected by the OS as two display adapters, with either of them becoming primary (head 0). Haven't you come across systems where people used crappy PCI VGA cards on systems with onboard video, so as to add more display heads without having many AGP slots? it's the same. So you install both, the GeForce PhysX driver, make it render PhysX, voila! your GeForce card turned into a physics card a-la Ageia PhysX card.
