Hello there, Long story short. I'm a skint student. starting my 4th year of uni to do 3D animation using Maya, and also some Sound Production with Pro Tools. Is the 13" good enough? how well does the HD4000 handle hi res renders of video? I'll be doing my honours project on which ever machine I buy so the final product is most important. So, is the 13" up to the job? and how much better on a scale of say 1-10 would the 15" with a seperate GPU handle the job? Also, If the 13" Pro IS good enough, would anyone recommend the Air instead? Thanks!
