So, I need a new Mac that can also boot into Windows. I have to use a Windows stats program that really needs the dual core processors (Mplus 4.2). I need as much horsepower as possible but have a limited budget. I'm thinking either the 17in iMac 2.0Ghz or the White Macbook 2.0Ghz. I'd get 2 GB of RAM in either. I just want to know whether folks know of any performance related differences between the two besides the GPU issue, which does not concern me. I looked online and it appears they have the same CPU, frontside bus, etc. But, I want to make sure. If there are no differences, I might get the Macbook for the portability. Thanks!
