Hi all. I need to upgrade to a mobile editing solution so I'm into buying a MBP. I am curretly looking at three models. The early 2012 2,4 GHz Quad-Core Intel Core i7 AMD Radeon HD 6770 1GB 8GB Ram 1333MHz 750GB SATA Hard Drive 5400-rpm The late 2012 2,3 GHz Quad-Core Intel Core i7 4 GB 1 600 MHz 500 GB hårddisk 5 400 rpm NVIDIA GeForce GT 650M 512 MB Late 2012 2,6 Quad i7 8GB 1600 MHz 750gb 5400 rpm NVIDIA GeForce GT 650M 1 GB To all of the above I want to put in 16GB 1600Mhz RAM and 256SSD the top one is the cheapest with the price rising in the same order. Im doing editing and after effects so I'm mainly wondering if its better with nvidia gt 650m 512mb or amd 6770m 1gb? Also... for the price of the upgraded Late 2,6 Quad (after I installed SSD and RAM) I can buy a 15' 512SSD, 16GB retina but I dont like the limited upgrade options. I like to be able to change things myself (battery, ram etc) and in a retina everythings soldered to the board. Thanks in advance.
