Quite a few people are expressing keen interest in using GPUs for other 
things besides graphics.  Here are a few links:

http://www.gpgpu.org  - General Purpose Computation Using Graphics 
wwwcg.in.tum.de/Research/data/Publications/sig03.pdf  - paper on 
implementing various linear algebra operations on GPUs
http://www.eyetap.org/about_us/people/fungja/research/ - cool paper on 
using GPUs for computer vision projects
