Hello Everyone, I am in the process of buying my first apple laptop. All of my other computers are desktops, including my 2012 mac pro. I am in the market for a mac book pro for school use, strictly for computer science/app development and some minor video editing. I am currently in the process of deciding witch laptop i should go with.. Option 1.) mac book pro 15 inch retina 2.6ghz i7 (3.6 ghz turbo) 8GB ram nvidia GeForce GT 650M with 1GB of GDDR5 memory, 512 ssd. option 2.) mac book pro non-retina display 2.7 i7 (3.7Ghz turbo) 8Gb ram GeForce GT 650M with 1GB of GDDR5 memory, 1tb HHD 5400 RPM I am currently leaning with option 1 because i will not have as much of a bottleneck when it comes to my hard drives speeds. But the only limiting factor of the retina model is i can not upgrade ram (if im not mistaking) however, i think i should be fine with 8GB.. Also, is there a huge difference in processor speeds? .1GHz difference should not make much of a night and day difference.. When it comes to projects that require a bit more rendering power, i do own a 12-core mac pro with 40GB of ram, worst comes to worst. So im not looking for a complete powerhouse laptop like my mac pro. Any advice is greatly appreciated! Thanks guys!
