Don't kid yourself
. World of Warcraft is almost six years old, and all Cataclsym significantly adds is a new lighting effect and updated water. Out of curiousity, I watched a video from Blizzard's Cataclsym presentation and I saw the graphic improvements. Still doesn't exactly bring WoW up to 2010. I'm pretty sure my MacBook Pro could run Cataclsym fine in Boot Camp and at half the framerate in Mac OS, but I haven't played WoW for years, other than trying the game for less than a hour total to find out how the Mac client ran a year or two ago.
