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