with the exception of CUDA performance which hasnt been hobled

Diving through this thread seems to confirm the info Rob Birnholz picked up at NAB that the GTX cards are optimized for writing to screen and hobbled at writing data back to the CPU, compared to the Quadro cards which are more generalized graphics processors than "just" display cards.

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.
