I really like this computer, but I'm not too sure if it suits my need. I'm a software student that has an iMac as my primary machine. Even thought I do have a primary powerful machine, I still would like to run programs like CAD, XCodes... The thing is that I really want to buy it on the first day it comes out....is there any type of website that would test to see how powerful the computer is?? Or is the something "quick" I could download in stores to test the Mac before I buy it?
