I don't think AMD cards use it. But The program PhysX runs Physx on your CPU. So if you play games that use Physx I still recommend keeping it. The PhysX that the Graphics Cards use it Advanced PhysX. Rate Good if this helped.

^That is correct even though a AMD does not use Physx some games still require it to run. Running a AMD GPU just means that Physx will run on the CPU and not GPU. Uninstalling it could make some of your games not run.
Yeah you can use it, it uses your CPU, I have a Radeon 7950 and use PhysX with my CPU. Long as it isn't causing issues and you can use it or want to then by all means keep it
