I am planning on purchasing a 15.4" Macbook Pro. I'm going to be using it for a graphic arts major. I plan on using it for: -Word processing -Design (Photoshop, Illustrator, etc) -Movie Editing (After Effects, Premiere, etc) -3D Rendering -Gaming -Music -Internet -Email -Other tasks Many of these require more than one heavy program to run at a time, and I don't know what 15" Macbook Pro will meet my needs without being overdone. Apple's online assistance is basically nonexistent, so I don't know who to go to with my questions. Should I go with the i5 2.4, the i5 2.53, or the i7 2.66? And is the High Resolution screen upgrade worth the $100 dollars if I'm going into graphic design? Also, where can I find the best deal for 6 or 8gb RAM upgrade instead of Apple's $400? Thanks for all your help!
