Hey everyone I just purchased a RMBP from Best Buy because of the sale they are having. I was able to get it for a final price of $2,782.00 which include tax! This is saving me about $180. However, I have been thinking. Is 8gb enough? If I want to upgrade to 16gb of Ram I will have to purchase the computer from the apple store which will have a final price of $3,178. So here's my question to you: is upgrading the Ram to 16 Gb worth $400 dollars in your opinion? Thanks!
