I'm currently using a 9800GT, but I have a couple of Questions regarding PhysX
1) I can't seem to find any benchmarks, but if I run a Physx enabled game does anyone know what the performance hit would be like? Is it really worth it on a single card?
2) I'm of the understanding that a second Nvidia card can be set to solely concentrate on Physx X while the main card runs the graphics, but my Motherboard a Neo 2 FR is ATI crossfire. I know I can't run SLI (obvious), but is it possible to run a second Nvidia card just for PhysX?
