    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?

    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..

    Just for curiosity how much of a hit will you take on re-selling that PC?

    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.
