Guys, need advice I have new MBP 15" with i7 QC (mid 2012). I want to upgrade RAM, HDD ... my question is : 1. RAM : OWC, CORSAIR, CRUCIAL or?? 8GB or 16GB? or ?? 2. SSD (maybe 120gb or 240gb), SAMBUNG? OWC? Corsair? or ?? I'm just using my macbook for office and developer apps (mobile, web, c# banking). I have retina 13" with 8GB SSD 240 before, but this screen very small... i need large screen.
