would be very cool if some big software development house such as Adobe would figure out a way to do this.. maybe not all operations but just offloading the heavier operations from the cpu if possible, would be good to know that the most expensive part of the computer would be used for more than gaming =)

"Modern graphics processing units (GPU) are far more complex than contemporary central processing units (CPUs)"

Not even close... just because they have more transistors? I don’t think designing a pipeline and vertex processor, and then REPLICATE it several times is very complex....
I will not even talk about the AA "engine" that have been the same since Geforce4 < COPY PASTE

"and even though they work on much lower frequencies, the number of operations they can perform at once may exceed than of the CPUs."

Not even close, CPU can process anything throne at it very fast, look at the software that exists in the all world.
GPU is more like an DSP, do that and only that fast enough.
