Hey guys, as of right now I play WoW on my base 13' mid 2010 MBP. I noticed that it gets a little hot but I heard its fine because the aluminum body dissipates the heat or something. Should I be doing anything about the heat? Also, I do max fps at 27 but I lag a little outside Orgrimmar where lots of people PvP and inside major cities. What can I do to upgrade my MBP to make WoW run smoother, especially when Cataclysm launches. As of right now I play on the lowest possible setting but I'd rather play at middle settings if I can. I can spend up to $150-$200 to do whatever I need. Thanks for the input, in advance!
