Hey guys, I need some help deciding what to do. I currently own a 13" late 2013 RMBP, with 8gb ram and 256gb ssd. Lately I have started getting into Starcraft 2 and WoW again. My current Mac does okay at both but nothing special. Recently someone offered me a trade to a June 2012 15" RMBP. Same 8gb of ram and 256gb ssd but it has a 650m and an i7 quad core processor. I am just wondering if this would be a good trade and if I would see a considerable difference in the gaming I am experiencing on the integrated chip vs the dedicated. Oh and for the record I don't travel much. I originally bought the 13" for portability but I rarely take it with me. I normally play games and watch movies along with internet browsing. Though I would like to move it every once and awhile. Also does it make a difference going from PCI-e ssd to just a normal ssd? Thanks for your help.
