Hi guys..so I cannot wait for this iMac refresh. I will be picking one up for sure (haven't decided if it will be a 27inch monster or the 21). My question is this, if I will be using my Mac mostly for music production in Logic/Garageband/FL Studio/ etc. should i get something with a fast processor or memory? From what I read it's a little bit of both...can someone please help a noob out? thank you in advance!
