Hi, Please I'm having problems deciding on the macbook to buy. Should I get the macbook pro 13 2012 or Macbook pro 15 2011? I want to use it mainly for heavy Photo editing with Appeture, Photoshop and Lightroom. And also occassional gaming like Wow,Diablo,COD, crysis. etc. The reason I want the 13 of 2012 is cos of usb 3.0 which will help me in transferring large files for editing. The downside is no dedicated graphics card and overheating. I want the 15 of 2011 cos of dedicated graphic card and the bigger screen. Downside is no usb 3.0. Please which should I buy, the 15 inch 2012 is out of my budget. Please help.
