He's been at Apple before. Doubt he'll go back to a place he's been before unless he thinks the landscape has changed enough he can have a really big impact again. I don't think thats the case at Apple.
No - I think he'll go to Nvidia, because he hasn't been there before, hasn't really worked on GPU's before, and because I think GPU's could gain a lot of performance by having someone look at optimizing the big picture, adding the right abstraction layers, and generally making a GPU more CPU-like to allow more execution to be moved to it more easily.

He did two separate stints at AMD, and if the rumors of Apple switching the Mac to the A-series are true (which they probably are) then there will be some very interesting problems to solve over the next few years.
You could make this same argument for any sufficiently mature architecture, but the reality is that there's always something new around the corner. I can't imagine the processor in an eventual ARM-based Mac Pro will look much like the one in the first ARM-based MacBook, you know?
