I'm going to buy a 2.66 macpro to play games in both OSX and eventually boot camp. I have read some disturbing things about the X1900 XT. Overheating, fan noise, video 'disturbances/artifacts' and the card eventually burning out...pretty scary. Think I should I just get the stock 7300 GT and wait for a better card to come out or is there a better card already available? P.S- No cards that will break the bank. $400-$500 is the most I will spend.
