As I said this is your narrative. A card "wins" if it is largely faster than the competition. 3080 and 6800XT are trading blows and even on the same games it depends on the scene. Eg HU has 3080 faster at hitman 2 4k whereas TPU and GN have the 6800XT ahead. 3080 has a 4k edge on average but it is behind on far too many titles to say it wins because frankly, it is not clear.Multi game averages from multiple sites show it ahead. Pointing out a few specific titles is 'creating a narrative you want to believe.'
Maybe, maybe not. AMD has had consoles for a long time now and you'd think you would already see amazing optimizations on current hardware. I bought AMD before on that premise and it didn't really materialize. We'll see. I'm evaluating it on how things stand now. Honestly both are going to see improvements through driver optimizations. Its early days for the ampere drivers as well.
Sure, I have a ULMB monitor as well and know all about it. Still they both tend to be more than fast enough on the titles that matter for strobing displays to work well at 1440p. I'm less concerned about single player adventure type games with it. Adaptive sync is more important for those generally.
And as I said, if you want to see the console effect, look no further than Hawaii vs Kepler or Maxwell to see how well it performed even against a newer and more gaming focused architecture, thanks to being a graphics arch present in consoles. This time it will be no different, console devs will scramble to get every bit of performance out of their hardware.
