Hi Kosala,
If your interested in trying out CUDA and dont have a nvidia card you could
always use the
CUDA emulator. Also you don't need an expensive nvidia card. All nvidia
cards above the Geforce 8000 series supports it
Check out
http://www.nvidia.com/object/cuda_learn_products.html
GPGPU is a lot closer. Check out
http://gpgpu.org/ Its a relatively new area
and there are tons of research going on.
True at the moment that most programs that run using CUDA (and others
similar to CUDA) are scientific applications
but with more FLOPS and higher bandwidth than the CPU, the fact that we
could use the GPU for genreal purpose computing and not only for gaming and
graphics stuff does seem logical and very intersting.

Indika
