To me this is more worrying for GPU's at future process nodes. Most modern video games push my i5-4570 to reasonable levels, but my R9 290 uses over 3X the powe

To me this is more worrying for GPU's at future process nodes. Most modern video games push my i5-4570 to reasonable levels, but my R9 290 uses over 3X the power (and generates 3X the heat). If electromigration is much more prominent due to feature size we could see GPU's dying a lot faster than CPU's.
