Hello TH, I remember reading about this being possible but I searched and couldn't find out if it was possible still. I have a XFX R9 280X and a PNY 560ti. Is it possible to use them at the same time? I am currently using my CPU for Borderlands 2 PhysX and it does pretty well, until I start blowing crap up, fps drops to 11.2 in a hurry.. Anyways thanks in advance!
