My understanding has limited Guild Wars 2 for only windows users. I have a 27 inch mac that runs WoW better than any pc I have encountered.
(please don't make this a pc vs. mac topic)
In lieu of the upcoming beta (weeks or months from now) and the game release, I bootcamped windows onto my Mac because I won't let that stop me and didn't want to have to worry about rushing to get a copy of windows to be able to join in the greatness of beta.
In addition to other uses, the main reason I put Windows on my mac was to support GW2 because every time i see a video of the game my blood pressure increases. I fear one of these days I will have a heart attack from it.
My understanding of bootcamp has left me to believe that my computer's full resources are used to run Windows so that said is it going to be sufficient in running GW2?
2.8 GHz Intel Core i5
ATI Radeon HD 5750
4 GB 1333 Mhz DDR3
With my luck they will announce that there will be mac support for gw2 in the next week or better yet someone will tell me they already have and I missed it.
