For those who wanted to know the super duper minimum spec to run Diablo 3:

I have tested on my laptop: i5-520m with Intel HD Graphic.
Setting:
800x600, everything else disabled or LOW. Smooth gameplay except part where you fight a big group of enemies. But I cant tell if that's actually due to the laptop or internet connection.
