Long time lurker here who is lost in a tornado of specs, and prices. I'd really appreciate some buying advice! Long story short: Currently have a base model mid 2012 15" rMBP (2.3GHz i7, 8GB ram, 256GB flash). Want to use the iMac for University when I'm at home/as the home computer, I don't like being hunched over the rMBP; screen isn't big enough to easily work on assignments (even with split view/increasing useable desktop space) and I don't want to use an external display. My usage is pretty standard, MS Office/web browsing/email/streaming video/home photo editing/normal usage. I'm a casual gamer, things like cities: skylines, telltale games, old nostalgia type things (everything else played on consoles). I keep the majority of my media on external drives due to limited storage in rMBP - would be nice to have it all on the iMac. I appreciate that both iMacs are probably overkill, I made the mistake of buying a 2009 13" MBP without considering future needs and ended up regretting it after a year and don't want to do the same again. I had decided on the following: 5K 27" (3.2GHz i5, 8GB ram, 256GB flash, R9 M390, Apple HE store includes 3 years AppleCare without phone support) - £1,478.40 - I'd keep a media drive connected with this option HOWEVER I found the following from an authorised reseller: 5K 27" (3.3GHz i5, 8GB ram, 2TB Fusion, R9 M395) - £1580 - 1 Year AppleCare. (Would be £1,627.20 through Apple with education discount but with 3 years AppleCare) Is the M395 going to be mega overkill for me? Should I go with the M390, or even the M380? If I got the M395 is it likely I'd regret not having the extended AppleCare?
