I'd have thought AMD could bridge the use of CPU and GPU processing powers - when the graphics card isn't at a percentage of use, so it causes a reasonable speed up in general processing.

Sorry if I sound dumb, but I want to fill a void here - what architects do GPUs work with? Or does it simply universally process code? I'm not too sure how it's done ^^'

On a side note: what does GPGPU Stand for??
