Personal opinion, as a gamer, I went with the 5660. I wanted the absolute fastest processor possible, cause I hate lag more than anything. The screen is still 15 inches, equivalent to a 17" desktop. So slightly larger screen size is not that important to me. If you are set up at home, you have another CRT for gaming anyway. The higher clock speed of the GPU makes for better gaming, I don't know if I could tell either, but benchmarks show it is better. It is (ever so slightly) more portable. And I didn't need a TV tuner, MP3 player, or second hard drive. 40G is plenty for me. So those are my personal insights. I'd say the 5660 is THE gamer, the 8886 is THE complete desktop replacement.
