I am a college student and currently doing Graphic Design and Product Design, my work load can get heavy and my macbook pro 13inch 2011 slows down when the going gets tough, I'm looking for a larger display and maybe another machine all together. There are three options really. Firstly the 27inch mac with a 3.1ghz i5 processor, a Mac mini with the i7 dual core and maybe an ssd hooked up to a thunderbolt display (could use it for my macbook pro as an option swell) or the third option is to upgrade my macbook pro to 8gb ram and get a thunderbolt display. I have the apple keyboard and magic mouse already also. What do you guys think would be the best option?
