I have a 2009 13" MBP 2.26 C2D, 4 GB RAM, and I am looking to upgrade to the 15" 2011, low end model. Now I am a college student, and I do a lot of webcaming(iChat), MS Office, Firefox, movie watching, and looking at large(100+ pgs) PDFs(>100MB), and yes, I do a lot of this at once. I can have about 7 or 8 things open at once. So far, my computer is holding up, but sometimes it can hang. Pretty soon I am also going to start playing some games, and I know the integrated graphics are a step up from my 9400M. I am really looking forward to the 15" screen, but I am wondering if I will really see a difference in my day to day activities with at 2.0 Core i7 Quad. I know that an i7 Quad is overkill for me, but I believe in resale value and future proofing. Also, do you think it would be worth it do upgrade the screen resolution? Thanks in advance!
