Hi, so I'm getting a GPU upgrade as well as a PSU upgrade. I'll be getting an EVGA 500W power supply, and I was planning on upgrading my nVidia GT 630 to the ASUS 750Ti OC edition. I know the new PSU will have enough power to run the 750Ti, but will I be able to use the 630 alongside it for physx rendering? And would I even want to do that?
