Thats the physex chip. It was primarily used to render physics, until the load was moved onto the CPU and GPU

 

Thats a pretty old card youve got there

It's a display chip for driving digital displays and has RAMDAC for driving analog displays. Was primarily done to simplify the already big G80 chip iirc.

Would have been cool, but no that wasn't case.

Nope, physx will be done on the GPU. That thing is a combination of a RAMDAC and i/o

And some i/o stuff including sli stuff.
