How much difference in performance am I going to notice?

Back in 2011, following a lightning strike, I replaced my Mac Pro with a 27" iMac.

I specced it to the best possible at the time, it's the 3.4GHz i7 version which I put 16Gb RAM into. It's got the 250Gb SSD and I've replaced the 2Tb mechanical drive with a 4Tb mechanical drive. It's got the 2048Mb AMD Radeon HD 6970M graphics.

I do a lot of text work and I share media around my house via a massive iTunes library. The only game I play is Eve Online. I do simple video editing in iMovie, basic photo editing using Photoshop and I have a couple of Parallels VMs which get occasional use.

I'm replacing it with the new 27" iMac. I've gone for the 4.2GHz i7 version with the Radeon Pro 580 and a 1Tb SSD. I'll be adding an extra 32Gb RAM to take me up to 40Gb and my media library has already been moved to a Drobo 5C which I'm currently accessing via USB2 and I'm hoping will be somewhat faster on the USB-C interface.

Realistically, how much difference am I going to notice in general use? This machine isn't actually a slouch, it still copes with everything I throw at it without missing a beat - It's a case of not actually needing to upgrade, it's just that I want to!

Nobody else has gone from a 2011 iMac to a 2017 or has any thoughts?

I went from a 2012 i7 with 32GB of RAM and a 1TB Fusion drive to the 2017 i7/580 and 40GB RAM/1TB SSD and I have noticed a substantial difference.

I went from a 2009 i5 (upgraded with SSD) to a 2017 i5 (w/ SSD). The differences in speed are barely noticeably. I do light photo (Pixemator and Affinity), Logic and Final Cut editing. The main difference for me is the nicer screen and games in Steam are actually playable now. Otherwise performance is more or less the same on most tasks.

a 2011 machine with an SSD is capable machine. Only reason I'm upgrading is the retina screen and going from 21.5 > 27" kind of makes if worthwhile but i know in my heart i could carry on as I am. Too late to go back now :)
