Usually when you "upgrade" your laptop, you buy a new one. You can't replace laptop components as readily as their desktop counterparts. Dunno too much about good Sandy Bridge chips in laptops, but an Intel Core i7-2670QM like DefenderX's is pretty decent for many games in Dolphin, just watch out for heating issues. Still, you probably won't get full-speed SMG2 with LLE audio, but most other games should be a breeze.
