I had a Radeon VII I used on my MacPro5,1 that I would dual boot to Windows, which worked great with the LG Ultrafine 4K display (21.5", 4096x2304).
I upgraded to a LG 5K (same DPI, 27", 5120x2880) with the gc-titan-ridge thunderbolt card, but that was sort of a pain on an unsupported machine so I am moving to a M1 Mac mini + Thunderbolt PC. Hoping to drive it with a 3080, but I think it should be fine.
For any fast paced competitive games, you should be able to drive 60fps with the right hardware, but at the same time you will be held back by the lack of a greater than 60hz refresh rate.
