I know CUDA is tied to NVIDIA, but I can not figure out where to begin
with OpenCL. There is one available for Mac, one for NVIDIA, and if I
am right one for ATI too. Windows has its own API called
DirectCompute.
However the kernel based programming paradigm is more or less the same
in both CUDA and OpenCL. So even if one does not work out well,
porting to the other wont be difficult.

I know it wont be easy. Thankfully I have this big dev group to help me out :)

Okay. But I think the whole point of GPU computing is to aid in the
most CPU intensive tasks. I think rendering would be the top
candidate, and all the computational parts that make UI less
responsive
