Hi everyone. I will be entering college this upcoming year as a music composition major and will be investing in a Macbook Pro definitely a 15 inch, however I don't know if I want to go with a Retina or Regular model (that is if I will even be able to get a retina model before college). I will mainly be using it for school work but will also want to use it for Logic and MainStage. My main question is will 8GB of RAM be enough? I am not exactly sure how much RAM audio applications use and would like to keep the cost of the Retina model down as much as possible (even though I will be going for the 500 GB of SSD if I do choose it...) And also, the reason why I turn to you guys is because I feel as though even though the Apple store employees are supposed to be helpful, they always try to talk me into more expensive models and talk to me as though I don't know anything about computers. Thanks for your help.
