don't seem to have a big price difference between the two. For home user main collecting DSLR photos in Photos app, 500Gb on iCloud library, occasional tweak of raw files, managing emails, and virtualising Windows, will there be any perceptible difference? Any perks with ECC RAM? Does iMac Pro suck up lots of power when idling? I'm attracted to the space grey body of the iMac Pro though. Appreciate your advice.
