Hello everyone, I am currently looking to replace my outdated PowerBook but I am overwhelmed by all the options available! I am a graphic design student, and I want to be able to do large scale print work in photoshop (12×18" @ 300dpi and up) without excessive slowdown. I'm really interested in the Macbook pro (because of its portability), and I wanted to if the pro line could handle such large files, or if I'm better off served going with a desktop. I was also considering building my own pc, but I've had very poor experience with Windows in the past. Also, are upgrades such as 8g ram or SSD's worth it on the Macbook Pro? Thanks a lot, I really need some expert opinions on this!
