Most APUs are bad for games right now on Dolphin. Ultra low voltage CPUs are simply out of the question. You´ll have more chances with i5-4200M (note that I put the M suffix instead of U, since M is generally stronger than U models when talking about Dolphin).
I found an HP envy 15 that indeed has that processor, the bad thing is that costs US$542, more or less.
