I read 2 pages of this thread, and got distracted by what I wanted to say.
Driver overhead seems to be the limiting factor in multi gpu solutions like this. Seems like at some point there will be one card that won't handle any 3d acceleration, but instead will handle the distribution of the work load to the other 4 (32) cards.
