So I picked up a GTX1070 recently, and have been using it under Windows Bootcamp - very happy with the card. Expecting Pascal drivers to arrive "soon" In the meantime I'd like to be able to use OSX. Currently, I'm rip and replacing the GTX1070 with a GT120 (as they will not co-exist in Windows) every time I want to use OSX. I also have a GTX680 (EVGA 2GB, flashed) lying around. Could I run the GTX680 (without PCI-E power cables) alongside the GTX1070? I know the GTX1070 won't POST without the PCI-E power cables connected. Not sure about the EVGA GTX680.... Alternatively - any nice way to have the GTX1070 and GT120 work at the same time (under Windows)?
