well my desktop just crapped out on me and i really don't want to invest money to rebuild it. I was looking at the imacs but my one concern is about gaming. I really only play WoW but I also want the option to maybe play something newer. I am a little concerned with Macs lack of video cards and in order to get at least 512mb i have to spend 2k. Do macs not need that extra video power? Just want some opinions.
