I have a 2013 iMac 5k 27". I was really hoping Apple would release a new iMac this year so I could upgrade, but that didn't happen. Wondering now whether I should upgrade to the iMac Pro or iMac 2017 now, or wait to see what happens in 2019. My priorities: As quiet/silent as possible (I do a lot of audio recording/screencasts throughout the day; right now the fan in my 2013 iMac comes on a lot when I'm using Screenflow and other recording apps) Fast with photo editing. My 2013 iMac is a bit laggy with Lightroom and Photoshop. I don't do any video editing and don't plan to. The iMac Pro might be overkill, but this will be used for work and the price isn't a huge factor. From what I've read it is very quiet, and more than fast enough for photo editing. And this is a minor factor, but have to say I LOVE the space grey color. Other options would be to go with a 2017 iMac or just wait. What do you think?
