What is a Dedicated PHYSX card?

[mrroguesr]

Hello,
Do you think that the NVIDIA GeForce GTX 470 1.2GB would benefit from a NVIDIA GeForce GT 220 1GB 16X PCI Express Dedicated PHYSX card?

only in the games that support GPU accelerated PhysX, though the GTX 470 should have enough power to do it and render the game

For more intense physX games, the 220 may actually end up as a bottleneck to performance, and could reduce frame rates.
