So, I'm running an early-2011 MBP with an i5 2.3GHz and 4GB ram and running Logic Pro X. I'm going to be upgrading this machine soon, but not sure if I want to go with just 8GB or spend on a full 16GB upgrade. The main thing is I use this for practicing with the covers posted in the Practice Room as well as on school assignments. Eventually, it's gonna be turned over to my wife when I graduate, probably used as a storage and backup device, and I'm picking up a brand new model. Do you all think 8GB would be enough? Or will I just want to upgrade later on anyways?
