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. http://ati.amd.com/technology/streamcomputing/product_firestream_9250.html SDK: http://ati.amd.com/technology/streamcomputing/sdkdwnld.html -- With our best regards, //Maurice W.
