Do I need to uninstall PhysX along with drivers?

I'm about to upgrade my GPU (going from gtx 260 to gtx560ti). Since I am required to delete my current drivers, I was wondering whether I should uninstall my PhysX drivers as well?



Thanks in advance!|||No real need to, Nvidia uses unified drivers. The GTX 260 and GTX 560 ti use the same drivers.|||Yes, uninstall those as well and then download and install the latest drivers from the NVIDIA website.
