I bought a 15" MBP a couple days ago (05/31). I have never really used a Mac until now, because I'm tired of the crappy quality PCs and immenent slow downs. I can say that im thrilled with my decision and will never go back. This has been a big aid to my music career. Anyways I'm not too tech savvy, but I want to make sure I buy the right RAM. I believe it's the mid-2012 model 2.6GHz 15" MBP with 4GB of 1600GHz DDR3 RAM I thought to myself since most of my DaW programs require 4GB of RAM and I do a lot of multitasking. I should go with 16gb of RAM (two 8gb). I read on MacRumors guide that CL9 Ram is best but I'm not sure. I heard good things about Crucial and Kingston, but which one would be best? Price is not an issue. My friends say to find Samsung memory but I've never seen such :S Aswell can apple install it for me? I appreciate the help guys. Thank you in advance for the recommendations.
