Some early stats from Folding@Home.

GPU - 35 Teraflops, 532 active machines (up to 1064 ATI GPUs if each machine is setup in SLI configuration).

Hmmm... (conservatively) up to $2.4 million could buy the graphics cards for 140+ Teraflops, but then you got lotsa motherboards & space & power costs.

It will be interesting to see what the PS3 or XBOX 360 brings as far as crunching per dollar?

Then again, in five years, Intel could possibly teraflop on a single chip.

is where more of the GPU conversation was being held.

With AMD/ATI releasing a programming interface for their cards geared to non graphics use - and nVidia doing something similar; it should be easier for the next set of DC gpu client programmers.

Looks like it'll be an interesting next few years.
