Quite a lot of people. I know of at least 1 brand of voice logger that 
use these boards for real-time compression. It was pretty much necessary

Take a look at  brookgpu, 
http://graphics.stanford.edu/projects/brookgpu/index.html. It's a 
compiler for Brook (C with streams) for nvidia,ati GPUs. According to 
one of the PPT on the site, it's possible to get 2-3x speed up over the CPU.
