I just bought an XFX 5850, I had an Asus 4890 that broke down. I am trying to launch Dragons Age, or Mass Effect 2 and I am told "Error initializing Physx, please visit nvidia.com/physx for updated drivers." what doesn't make sense to me is installing http://www.nvidia.com/object/physx-9.10.0224-driver.html with an ATI card, maybe I'm wrong, thats why I am asking.
