Hey, so recently my old 2011 MacBook has kicked the bucket. I'm looking into the 5K 27" iMac to replace my setup as I don't need it to be very mobile. Also looking to upgrade to 4.0gHz QC i7 and currently 16GB of RAM (advice on whether it's worth going up to 32GB? I'll be using NI libraries and samples but this ties into a later question too...) Questions... 1. Is this an ideal setup for what I'm after? I'll be sticking with the 2TB fusion drive, would this be enough? Are there any suggestions I should use to maximize my processing in favour of a music production setup? 2. I've read a lot about people running samples/sample libraries off hard-drives to free up processing power. Would this be appropriate to use in this situation? If I ran my sample library from -say - a 1TB external hard-drive would this negate the need to have other upgrades in areas of the iMac mentioned earlier? 3. Furthermore - is it possible to run all plugins/samples/sample libraries off an external drive and purely run just the software and any live instruments into the the iMac through my audio itnerface? (This doesn't sound possible from my very untechnically-minded POV, only the sample library on the external HD makes sense but do educate me like a child if need be - I've got no idea on this stuff.) Anyway, thanks for reading. Any suggestions and advice is hugely appreciated - as I said I suck at this sort of stuff so anyone who's willing to give me a walk through all this would be great!
