Well, she's not playing it on anything now because she changed departments at work. Her old department gave her a Retina MacBook Pro! She was also able to wrangle admin access to that laptop out of her department's IT guy. She hasn't had such luck in the new place

Tom, I agree that the latest integrated Intel graphics are sufficient, particularly for SimCity, but like Tony I haven't really seen the 5000 series in the laptops I'm looking at. I haven't seen a $500 or less laptop with those chips.
So would the 640M and an Ivy Bridge Core i5 be sufficient for SimCity?
