I don't think you understand. There used to be a PhysX card. Nvidia bought the company, and is porting the physics engine to work on their GPUs. There will be a driver update for all 8800 users which will enable this physics engine in games which previously supported the PhysX processor and new games which use the PhysX API. There is no additional cost to you.
Additionally they're offering to let ATI support the API on their chips as well, so game developers won't have to code for six different physics engines.
The reason they can do this is GPU's are now a lot more like CPU's since they implemented shaders. You can run all sorts of code on them. And once this physics API is out there they'll be able to add stuff to future CPU's which will speed up the physics even more if need be.
