I am considering buying a larger external monitor for use on my MacBookPro. Currently I have a 17" monitor that I run Parallels(WinXP) full screen on which works well. Can anyone give me some feedback on their experience running Parallels with a 30 inch monitor connected to a MacBookPro? I am concerned that the over heads (CPU and memory) of the larger amount of graphics memory that needs to be handled will be significant. Thanks Nick
