We're in an exciting time where multithreading is the new frontier in computing evolution. GPU processing seems to be the answer to a specific group of problems in processing float point data in a program.
I have a 8800GTS (you can get these cheap now) that uses a pluggin called CUDA that enables my video card to process data on the GPU other than real time shading and geometry.

So far the things i've found interesting are the real time physics found in the free video game "Warmonger." The pluggin PhysX allows almost every object in level to be destructible or malleable. For example i was attempting to be a "camping fag" while sniping out a window. The other team caught on to me after and started shooting back. At first i felt safe because i was on the third floor of a building. The entire wall was chopped to pieces by their fire and the floor below me fell in as a missle struck from beneath. That's when i realized the entire building (except for some ibeam supports) was destructible. And it looked great because of the realtime physics acceleration.

What are your experiences with GPU acceleration? Do you use folding@home (cure cancer with your video card!)? Are you a math wiz and use your gpu for extreme calculations?

Currently excel dosn't use the GPU, but i hope it will someday...
