The Folding at Home GPU2 client is a High Performance folding client that takes advantage of GPU power through the use of CUDA technology on Nvidia GPU's, and ATI's Stream SDK on ATI GPU's.
The GPU2 client currently only works on Linux with Nvidia cards, as CUDA is much more stable on this platform.
