Hi,

I'm needing to sell my current desktop PC (modest spec - AMD 8750 8-core @ 4 GHz and 8 Gb GeForce 1080).

My current desktop and iMac 5K (late 2014) are similar in performance in X-Plane, with the iMac pulling slightly ahead (impressive considering the lack of video RAM, and mobile GPU). The iMac is anywhere up to ~10% faster (30 FPS vs. 25 FPS so you know what I'm talking about).

I don't play AAA games, though I do high-end PC flight simming (X-Plane, DCS).

Due to moving country, my new place is lacking space, and so I need to sell my old stuff and I'm thinking of getting the top spec iMac 5K (not iMac Pro).

I know it's "not a gaming PC" and I've had other people say "build a gaming PC", but that isn't an option.

For what I do, a Mac is great, with occasional Windows usage for work.

What I'm interested in is whether the new iMac has the graphical horsepower I'm looking for? In my fight sims I can run very high detail at 4K and get good performance (40-50 FPS, no stutters or lag). If the 580 can keep up, I'll put the order in.

The only reason I don't keep my current 5K is the GPU memory is a bit small, but I don't want to get a new iMac if the GPU is going to be a disappointment. Aside from the GPU and modern graphics requirements (mostly memory related), my current 5K is awesome.

Does anyone run DCS or X-Plane on an iMac with the Pro 580 GPU? How do you find it?
 
Thanks! My wallet is burning...
Presumably, you can reconstruct those tests on your 1080 machine, and see if a imac +radeon pro 580 is a step up or a step down. He did say that the 1080ti fared worse than the "Vega Frontier Edition" in a 12 core mac pro with an Xeon X5680..

I have no idea. I upgrade parts at a time so I didn't build the whole thing in one go. My last purchase for it was a 1080 a couple of years ago before prices went crazy.

Right now I'm thinking of upgrading the PC (Intel 9700K 3.6 GHz/Asus Strix Z390-F/16 Gb 4000 MHz/512 Gb M.2 SSD) and keeping both.
