Hello there. I'm looking to replace my aging 2007 MacBook with a brand new MacBook pro, but I am having trouble deciding between the higher spec'd 13" or the low end 15". Even after reading pages of specs, and the handy guides on MacRumors. Honestly, anything is better than the setup I have right now, but I want to make sure before I spend so much money. A little about my usage, I'll be primarily be working in PhotoShop, Illustrator, XCode, and either Lightroom or Apeture. I need an optical drive for school and I will eventually be buying an external monitor, so I don't want the retina, even though I spend so much time editing photos. I would like to try out some animation and find a good 3D modeling program to play with, and I would also like to have the capability to play Skyrim and League of Legends in bootcamp. Do I really need a dedicated graphics card for any of this? What kind of time difference am I looking at using photoshop heavily or Maya. The high spec'd 13" is looking better and better to me, and it is also a lot more portable. I would love some advice!
