Skip - you're right that GPUs offer tantalizing possibilities for J. I made sure to have an nVidia processor in the last PC I bought - the (C++-based) demos are very impressive. However, I have yet to grapple with learning enough about the CUDA libraries to think about how to integrate them into J.
I'll take a look at those videos.
