Hi, I am starting my degree at uni next year in graphic design. I currently own a 13" mbp but need a work horse for at home that will last me at least 3 years for my degree. My budget is roughly AU$3500 and basically have two options as I see it: 1: 27" iMac i7 w/ 8gb ram upgrade and possible HDD upgrade (this would leave me an odd AU$500 under budget) 2: 27" iMac i5 w/ 4gb ram + 27" acd (they don't sell the 24" anymore?) Is there any other good options that would suit my needs? I want it to be quite powerful for graphic processing but I also want as much screen real estate as possible. Thanks.
