I am about to buy the base 15" MBP and I'm about wondering a few things. I am thinking of ordering it with the 8GB of RAM option, and then putting in another 8GB myself to make it 16GB. So here are my questions: Can the base MBP have up to 16GB in it like the retina? If i choose the 8GB option, does it come with two 4GB sticks or one 8GB? Can anyone recommend an 8GB stick for the mid 2012 MBP (im in the UK) that they have had a good experience with? Am I better off buying it with the stock 4GB RAM and getting two 8GB sticks myself? Thanks.
