I love my 15" rMBP, but when I go to the store and see the 13" rMBP, I fall in love with that one, despite the lack of needed internals. Here are some concerns I would like you to help clarify so I can make a decision upon the announcement of the updated MBPs. Gaming: So I do some gaming, Bioshock, Half-Life, Counterstrike, Garry's mod. Mid-range graphics settings seeking at least 100 fps in the online games. This is the reason I got the 15" with the dGPU. Assuming the new 13" rMBP comes with the HD5000, it seems like that can handle gaming as well (as seen on the new MBA's). My concern with this is the CPU. Would there be a significant difference between a quad core and dual core when gaming? (assume both are the same speed) Final Cut Pro: I will modify and export non-HD videos up to 6 hours long. Obviously the CPU is a major factor that takes advantage of all 4 cores. Essentially does half the cores mean double the rendering export time? iPhoto: This is my second most used program with over 10,000 pictures. I dont think it has heavy CPU or GPU usage, but I want to make sure I wont notice a drop in performance moving to a dual core.
