Diving t= hrough 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 writi= ng data back to the CPU, compared to the Quadro cards which are more genera= lized graphics processors than "just" display cards.

That's exactly what I did when I put = the machine back together. The older ATI card is driving the display, the N= Vidia 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 max= ed out, slot-wise.

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