I currently have the late 2006 15" MBP with the following specs. 2.33 C2D 4GB ram 120GB HD ATI x1600 My battery is getting bad and is on 400+ cycles, but nothing else is wrong with it. I want to be able to play starcraft 2 when it comes out. I will also be using it for Graphics editing and College. Should I pick up a 13" MBP or the 15" inch MBP with the 9400m+9600m GT, or just wait for the new MPB refresh?
