So I am in my second semester at design school. I am doing a lot of CAD work on my mac and have a mid 2009 15" 512 GT macbook pro powering a 30" ACD. I have parallels with XP pro running and 4gb of ram. I haven't been so satisfied with the performance. I want to know if other people are using their MBP with the 30" for design work. Would the performance be better if I was using a 24 LED screen and more ram? Lastly, what mouse are you using for CAD. I am using the Magic mouse and its terrible. Thanks for the help.
