The current gen GPU's really cemented the idea in my head that fairly soon the GPU will just be the motherboard, and everything else will just tack onto it. The daughterboard becomes the motherboard.

They're just getting ludicrously large, and they use more power than the rest of the PC combined. Makes sense to me to just accept it, make it even bigger based around an absolutely enormous copper block, make it so that you just plug AC power straight into it and all of the components have a little home much like this M.2 Idea.
