Hey whats up everyone, I was wondering is the what the difference in the internals between the 13 or 15 inch retina as to how that would pertain to running logic pro and use it for recording and audio editing. Also, would you suggest the best processor or is the standard one good enough. Im pretty sure that the discreet graphics is not going to make a difference in the audio recording (or at least I would think not). I would lean towards the 13 inch cause I would use this as my everyday computer/school laptop, but I'm sure the 16 gigs of ram wouldn't hurt either. Thanks for your help.
