From someone who owns a 3080FE it's been a good card, but I bought it over over 16 months ago, so at the time £650 was the best price for any 3080 and the most I was personally willing to pay for a GPU, so Radeon 6800xt was out of the question at the time, as were any AIB 3080's. It has served me well at 3440x1440 and 4K resolutions, but I tend to be quite behind the curve in the games I play. I've only played 3 games that have ray tracing (WD:Legions, Riftbreaker and currently Deathloop) None of which have made me think I really need or am bothered about RT stuff just yet.
So, it depends on if you have many games that require ray tracing. If all the games you play are mainly rasterised then you could also consider either a Radeon 6800xt or for a bit more a 6900xt which will have stronger performance in rasterised games and have a bit more VRAM buffer for resolutions like 4K in the future.
dont want to derail the thread but what FPS are you getting in deathloop, I'm only at 1440p but seem to be struiggling to get over 100fps because of some type of bottleneck
