I wonder if it is possible to run both the AMD card and the GTX 470 at the same time using the AMD for screen draws and Open GL and keeping the NVidia for the CUDA cores acceleration of Premier Pro and others? Could the power supply of the MacPro 3.1 handle the load or would it need an external power supply for one of the GPUs?

That's exactly what I did when I put the machine back together. The older ATI card is driving the display, the NVidia is dead-headed in there for CUDA support. I put the ATI in one of the four-lane slots, and fed it power from the spare CD-ROM bay. Theres an AJA Kona LHe in there, too, and a eSATA card. So the machine is officially maxed out, slot-wise.

So far, so good, although honestly I really haven't done anything to push it, yet.
