Compared my current iMac with my coming iMac:

Late 2013 i7 @ 3.5 GHz, single core: 4209
vs.
Mid 2017 i7 @ 4.2 GHz, single core: 5610

= around 33% improvement. Not bad, but also not that huge an improvement (it's already 20% just comparing the clock)

Going from the nVidia GTX 780M (4 GB) to the Radeon Pro 580 (8 GB) will probably make more difference (to X-Plane 11 especially...)

Also RAM from 1600 MHz to 2400.

Can't wait!

I am particularly excited about x-plane 11 myself. It is inoperable with the 2gb GTX 680MX I have in my late 2012 iMac. I got the 8gb Radeon Pro 580, too.

Yeah, XP11 on my late 2013 and GTX 780M with 4 GB of VRAM runs... okay. I set it, on average, medium settings, but the very heavy sceneries (like pay ware AMS with ZL18 Photoscenery and extra auto-gen buildings) and having lots of clouds makes this Mac suffer quite a lot, with FPS dropping to the low twenties.

XP11 is "more taxing" than XP10 loading the same sceneries and aircraft, but does look even nicer than XP10.

I can't wait to have a go on the 580!!

new iMac (27-inch Retina Mid 2017) Intel Core i7-7700K @ 4.2 GHz (4 cores) single 5610/ multi 18945
old Mac Pro (Mid 2010) Intel Xeon W3680 @ 3.3 GHz (6 cores) single 2967/ multi 12573

Radeon RX 580 Series 131594
GeForce GTX 980 116261 on a PC? I doubt this is on a MacPro, I was really disappointed by this expensive card.

Time to replace my aging 4,1 > 5,1 flashed MacPro 2009?
I would like to buy a new iMac with an 512 GB SSD, Radeon 580 8 GB VRAM and 8 GB memory installed and add an external SSD drive and 16GB RAM

My current iMac (21.5", mid 2010, 3.2 GHz i3):
2355 single-core
4841 multi-core

My new iMac (27", mid 2017, 3.4 Ghz i5):
4740 single-core
13798 multi-core

Sounds like a decent upgrade to me!
