I'm looking to buy either the new high-end, 13" 2.9Ghz or the low end 15" 2.3Ghz. Whichever one I buy, I plan to remove the optical drive and put in a OWC 6g SSD (probably 120GB) and store data on the stock HD, and the OS and apps on the SSD. And whatever the stock RAM is, I'll definitely put 8GB in there as well. I also plan to use it mostly with a 27" Cinema display so I don't care that much about screen resolutions. I'd really love to save the money and buy the 13" model, but the biggest reason I'd want to buy the 15" model is because of the quad core processor and the discrete graphics card. I'm not a gamer though. The most intensive stuff I'd be doing on it is photo editing (LR mostly), but D800 files are huge and need plenty of processing power. But I'm hoping the super fast SSD will compensate for the dual core processor. So I'm mostly want to know is the "weaker" processor of the 13" model combined with its integrated graphics card going to be enough for the next several years, especially for intense photo applications like PS and LR. I rarely do video editing or gaming. Thanks for your replies!
