Hi, first post here and yes, it is another "how much memory should I buy?" thread. Well, I'm from Brazil and just ordered my first Mac (the i7 2.3 one, stock RAM/HDD), and I'm reallly excited about it. My girlfriend's sister is going to bring me it from US next week since it's a lot (think twice) more expensive to buy one around here. My question is: should I ask her to buy more RAM too? It will be used for browsing, office, light photo editing, common stuff (for what I'm sure 4GB is plenty). However I'd like to start recording some songs with a friend, nothing professional, just hobbyist. I just ordered an Apogee Duet 2, and plan to start messing with GarageBand. Since I have no prior experience with recording software requeriments, could some of the musicians out there suggest me how much RAM will I be using? - It's just home recording, I have no plans on building a studio, recording other bands, etc. - Plan to use GarageBand, may upgrade to Logic/ProTools if I find it too limiting. - I plan to buy NI's Komplete 8, mainly for Guitar Rig, Kontakt and StudioDrummer (we play alt/indie rock). May as well buy some piano library (Ivory or Gallaxy) since I'm a pianist. - Since my room has no treatment, we plan to record vocals and acoustic guitars on an real studio (maybe take the mini/duet and just use the acoustics there - is it possible? has anyone done it?) - I've never recorded anything before, so I'm not not sure how many tracks, but I guess it will be around... 20? (drums, vocals, maybe 3 guitars, bass, piano or synth). Obviously I plan to run Guitar Rig for the guitars/bass, StudioDrummer/EZDrummer for drums, Kontakt for piano, along with EQ, reverb, you know, this things tracks usually have but I still don't know about So, that's it. How much RAM should I buy/expect to use on a session? And please, please just don't say "more is always better". I don't want to spend $100 if I don't have to. I don't wanna spend $1 if I don't have to. I don't wanna have 16GB if I'll be using only 4, just to watch those 12GB doing nothing. I don't want to futureproof anything, I plan replacing the mini as AppleCare expires. I won't be using RAM disk or VMs. I don't wanna buy SSD for now. Thnaks!
