I am a first year uni student with a 5 year old laptop which is rubbish. I want to get a MacBook pro but which one ? I will be using it for everything. work inciding auto CAD, Internet, gameing, watching HD films. I will also be plugging it into a external monitor with wireless keyboard and mouse. This will be my first mac. Iam thinking the late 2011 base model 15" with 2.2ghz quad core i7, 512 graphics but with the optional upgrades to a 750gb @7200 rpm hard drive and the high res screen. Is 2.2ghz enough? Is 512mb graphics enough ? Or should I get the high end 15" mac with 2.4ghz and 1gb of graphics ?
