Hey guys I need some advise with this. I'm planning on upgrading my 21.5" 2011 baseline iMac and 13" 2013 rMBP, and consolidating with just one computer. Now I'm debating between the new 21.5" 4K and the 27" 5K. I can configure the 21.5" with 16 gigs of RAM, 256 gigs of SSD and of course no option for a discrete graphics card. That will be $1899. For $1999 I can get then the 27" with 8 gigs of RAM (to upgrade later by myself), 256 gigs of SSD and the AMD Radeon R9 M380. This is what I do: I don't play games on my computers at all, I play exclusively on consoles. The most demanding task will be photos editing coming from a full frame DSLR on Photos, Camera Bag and Pixelmator. And from time to time decoding MKV files and editing of some videos. It should last a couple of years. Now, is it too much difference going from the 21.5" 4K to the 27" 5K, apart from the screen? Which by the way both look fantastic at the Apple store. Is it stretching those $100 extra worth it? Any opinions are appreciated.
