Looking to upgrade my MBP 13" to a 15" retina. Have seen 2 specifications that are currently the same price in UK - £1999. MGXC2B/A - 2.5GHZ i7 with 512GB SSD, 16GB RAM (std price) or ME874B/A - 2.6GHZ with 1TB SSD, 16GB RAM, (reduced by £350 apparently) Seem to be pretty much identical in terms of graphics. From a quick search it appears the 2.5ghz is mid-2014 and the 2.6ghz is late 2013, but for double the storage it might be worth getting the older model? I'm not sure which processor is actually faster on paper. Which would be the better buy in terms of spec, or should I wait till black Friday at the end of the month and see what discounts Apple offer on MBP and use the saving to upgrade RAM? Probably won't mak much difference to daily use as I generally use for email/internet as well as some photo and gopro home video processing, but want to get the best possible at the time of purchase to give it longevity.
