I am wondering if that would be too much overkill for my sis. She only checks email and plays “casual” games like Peggle, and the Reflexive company games. However..she also likes to use Mame for simple games as well, which is cpu intensive (not gpu). I am wondering if 400 is pretty much the lowest I can get a decent notebook for playing the Mame emulator (old classics like pac-man, galaxian, puzzle bobble, etc)
