Hello! I just recently got my iMac(YAY!!!) and am very happy with it so far, but at highest settings in Wow I get around 22 FPS at default! My Imac has 4 Gigs of Ram, 1 TB Hard drive and a 3 GHz CPU and an 88800 GS! I updated all the things I could from the apple updater but was wondering if I also needed to update the graphics card manually like on pc`? I dont understand why the performance is so low, compared to desktop computers I have had that could run WoW fluently at highest settings much better.
