About a year ago, I ran F@H and got about 600 points with about 60 hours of folding (my CPU was a pretty good one, too.) The other day, nVidia released their new set of CUDA drivers (more on CUDA.) So, after I installed the drivers, I decided to try out the F@H GPU client. I left it on overnight (and increased the fan speed on my graphics card), and I got about 2000 points. This thing is ridiculously fast. I notice a bit more of a performance hit while doing things with F@H in the background, and I have to watch my GPU temps, because they get pretty high, but I would definitely recommend that anyone with a compatible card (GeForce 8 or higher, or Radeon x2000 series or higher) and that wants to contribute to the project to install the GPU client.
