Hi, I'm planning on buying a new Mac but I'm having trouble trying to decide on what to get. Its between the i7 Core iMac and the Quad-Core Mac Pro. What I'm using it for is to run AutoCAD, Photoshop, and other light 3D modeling software; and possibly some light gaming. I do need to run Windows 7 on the Mac since most of my software isn't available for Apple. My plan for the "Mac Pro" is to have 3 HDD, one dedicated to OSX, one dedicated to Windows 7, and the other for backing up the other two HDD and my MBA. I like the "Mac Pro" since it is easily upgradable and I can get new 1TB WD HDD for under $60 but the down side is the cost. The reason why I like the iMac is because of the low cost and its an all in one which will save me space but I don't know which will suit me better. For the "Mac Pro" I don't mind spending money on something that will last me for a while especially on how its easy to upgrade parts for it, so that's something to consider. Thanks.
