Indeed. Precisely the reason why I think it is so compelling.

There are about the same number of transistors in my GPU that are in  
my CPU. Most of the time most of those transistors in my GPU are just  
sitting there idling (99% of the time I do not do any intensive 3D  
tasks), it sure would be nice to be able to put them to use.

And you can easily add more GPUs to machine, not the case with CPUs....
