I read a little summary over on toms hardware of the cuda interface to nvidia graphics cards. i was intrigued by a post over on gizmodo about the GPU being used by -russian- hackers to break WPA and WPA2.
if you don't want to read all of it, i'll summarize: for certain things, a GPU can be at least 10x faster than the CPU.

FPU in your GPU with CUDA

My work has been having some educational presentations by the industry leaders in several areas... GPU's and massivly parallel (10, 100, 1000 or more cores) for CPUs are up and coming. Intel has some technology headed in that direction, NVIDIA is ahead, but Intel is good at what they do and tends to dominate when they decide to. So, look for a major shift in the way we think about cores in CPUs. Bottom line clock scaling for speed vs. watt is running out of steam (for now), so the industry is turning towards parallelism.
