So at this point, Im starting to wonder if I made the wrong choice in getting the 15" rMBP with only 8GB of RAM. Being on the forums, I hear OSX LOVES RAM. I am an avid gamer, and tend to have many programs open at a time, have large iPhoto and iTunes libraries (20GB and 300GB respectively); but then again, Mavericks is supposed to help with RAM usage right? Is RAM something I should be worried about for my future usage of my rMBP (2-3 years maybe), or is it something I should sell and trade up for now for the 16GB model. I just kind of feel I made a bad decision, and I either want confirmation of it or reassurance that it wont be a problem Thanks!
