Hey guys, I was wondering about using my old GT 640 as a PhysX card and my GTX 760 as my main card. How would I set this up? Would I set up my GTX 760 and install its drivers and then put in my 640 and set it to be my PhysX processor in the nvidia control panel, or would I have to install drivers for both of them to get them both to work? This was my first post, so go easy on me please. Thanks
