Ok so I'm finally making the switch to mac from the system in my sig. I'll still have that system as a backup, but for the most part I will be doing most of my day to day stuff on the mac. My question is: How well will a MacBook Pro with the x1600 and 2 gigs of ram run games like HL2, WoW, Pirates of the Burning Sea. I mainly play MMOs now, so I dont need to get 100fps for FPS games. Is it worth getting, or should I just stick with my pc and get vista and upgrades?
