6800 is faster in rasterization for sure, while 7700 XT gets the RT benefit. The question is how much of RT here are there will the new games utilise. I'm not saying full PT like CP 2077 but RT shadows or reflections that would blend into the game somewhere in the 'Medium' settings. Two main concerns would be:
a/ driver support period - with the rest of my system not upgradeable, I'd like to have it for a while
b/ if any new features will be better on/exclusive to RDNA3 - I do not stream at all, so AV1 is not an issue at all
On the other hand 6800 has 16 GB VRAM and when developers will agree that 8 GB era is over, they might go over the top with texture sizes - not to 10 or 12 GB, but probably all the way above 12 GB (case and point - Last of Us Part I). And usually better textures mean almost no to zero decrease in performance, so you could still use mega ultra hiper texture quality with mid-range GPU in 3 years, while RT is not really 6800's or 7700 XT's territory in Control released in 2019, not mentioning future releases, so I'd say full RT performance is no selling point at this price tier.
6800s supply is slowly drying up, basically only the XFX one is available with good pricing, I suppose due to being 340 mm long, but my case could easily accommodate, so that's not an issue. Hence a bit of a hurry, IF 6800 is a good choice. Otherwise, the 6700 10GB is still quite capable for what I'm playing recently (just finished God of War at 1440p (native, no FSR) with everyhing but shadows maxed out, decent 70 - 80 fps).
