I currently have the white macbook but it is very slow when I try to play the sims 3. This is one of the only reasons I use my computer so I feel it is pointless, thus I have decided to upgrade to a new mac. Which Mac would be best for gaming? I am open to any and all ideas (note: I am only considering a mac so don;t just say get a PC). Also if it would be best for me to pay extra for certain features or upgrades please specify. Thanks!
