My concern was WoW too but that base 15" 6490 is pathetic. NOT worth going up $600 IMO. I'm now in the market for an arrandale i7 + 330m since the 330m is better than the 6490. The "benchmarks" on the apple site are for the 6750.. but yeah pathetic graphics update. Sandy Bridge is awesome though lol. Also on WoW you're better off with a higher clocked dual core than a quad core, but that's just for WoW and most games.. Graphic intensive games utilize the quad core better but what's the use when the bottleneck would be the graphics.
