Before the explosion of power of modern video cards, manufacturers of graphics chips were thinking about using them for something else, to make specific and repetitive calculations in place of the central processor.
At NVidia, this technology is called CUDA.
The builder has just put a beta SDK and compilation tools online (for OS X 10.5.2).
To learn more about the CUDA, we recommend an article by Hardware.fr:

Note that many experts in cryptography do not think favourably about these developments, the GPU seems particularly well suited to breaking codes in a time that is acceptable to hackers.
