Personally i would go the AMD route with their latest Threadripper (I currently have their x1950 Threadripper) because Ue4 utilizes all cores when it comes to cooking, for the gpu you want to go with Nvidia and depending on your budget either their "gaming" line RTX 3090 or their professional Quattro line (Cant recommend any because i have only used RTX and GTX cards personally) 

As for the scene, that will entirely depend on what content you have, no card in the world will run literally anything in 1080p 60fps you can make even the fastest card in the world weep with sorrow if you build an unoptimized scene

Oh and would recommend at least 64Gb (honestly i would just go 128) of DDR4 3200mhz ram

And for storage go with at least a 5400mb/s Nvme m.2 SSD

Bust i must warn that even the highest specs wont remove the probability of running into issues

I would pick a high single core clock speed CPU like the Intel i9 12900K over a Threadripper if it’s just for running Aximmetry in real-time. Aximmetry isn’t optimized for multi-core performance, so the highest achievable single core speed will be what limits your total performance in the end. For building the scenes in UE4, like cooking and compiling shaders a Threadripper will be much faster of course. 

@twentystudios he did mention cooking projects so ue4 is most likely involved

@DeataProduction: Yeah, but I still think the 12900K would be the best compromise between these two separate uses.

Hello, 

I would say the 12900K is the better choice here. Since the main purpose of the rig is Aximmetry's performance. Sure the Threadripper will cook scenes faster, but the 12900K wouldn't be that far off and would give you a better overall Aximmetry experience because of the much higher single-core clock speed.
