Looking at AMD/ATI Firestream and 4850 pricing, it is not too bad:

AMD FIRESTREAM 9250 STREAM PROCESSOR (P/N: 100-505563)        $880
VISIONTEK RADEON HD4870X2 2GB PCI-E (P/N: 900250)                      $575
VISIONTEK RADEON HD 4870 512MB PCI-E (P/N: 900244)                     $355

The 4870 and X2 also run the AMD code.

So, given a decent machine, with 4 cores and a pair of the 4870X2, one
can achieve some pretty amazing GPU
performance levels for a system well under $4,000.

With dualX2s ( 4 GPU engines) around $4700 ( extra PSU capacity and
cooling is needed for that level).

I hear that AMD have a new Firestream coming, with the 48x0 family chips
on it, but that will likely be a bit on the pricier side..

Anyway, the Firestream has GPUs with Double-Precision Floating Point.
Something the  nVidia offerings do not.

Worth considering.
