Hey guys, So for the longest time I've been a huge anti-mac guy, and a big supporter of windows. That is until recently I've had a change of heart and I started looking at macs in detail and now I'm soooo ready to make the switch to a mac. However I am a little confused about the hardware specs that are customizable on the apple website. I'm most likely going to get a mac pro 13" because of portability and price (I'm a student) however I would like a really powerful mac pro because I don't want to be obsolete in less than a year. I was wondering why the 13" model has the highest GHz processor though. People keep saying the 17" and 15" are more powerful but when I go to buy a macbook pro online it says the 13" i7 macbook has a 2.7 GHz processor which is the highest option available. Even the most expensive 17" only has a 2.2GHz. Does that mean that the 13" is the fastest and best way to go?
