This is definitely not new news at all. The general-purpose graphics processing unit community has been active for quite some time, see gpgpu.org. I think Nvidia may be using this to just push their quad-gpu / SLI setup as it would be pretty hard for the main cpu to keep all of those gpu's busy 100% of the time. By offloading physics, and numeric solvers, etc, you can do some interesting things. Think of textures as your inputs, and render-targets as your feedback from the gpu. However, this is not new, as many of you have pointed out already.
