Hi Everyone, I'm looking to make some upgrades to a new 21.5" 4k iMac I'm planning on purchasing. I would like to upgrade the RAM to 16g and upgrade to a fusion drive. Are both these upgrades worthy? If I upgrade to fusion drive, I was thinking about upgrading to the 2T version since it has 128g of flash and the 1T only has 24g of flash. What do people think? I don't do any hard core stuff on my mac (no video processing), but I would like to use this new iMac for 8 or 9 years if I can push it that long. I mostly use Photos, Mail, iTunes, web browsing, MS Office, Google docs, and some Garage Band. I would like to possibly use some DJ'ing software and possibly Ableton in the future. I would probably also use iMovie at some point (I don't think I'll ever get to Final Cut pro). Thanks for your advice.
