if you are basing this in current prices, then i cant help you either, as current prices are messed up and not really a good metric to go by. the way i look at it, 3090. 4k, 3080, 2k guaranteed, and dabble in 4k if the card can handle the game being played, 3070, 2k guaranteed, and the 3060 1080p and dabble in 2k, again, if the card can handle the game being played. graphic settings are personal preference for the most part, but for me, they would be maxed in this example.
either way, for me i was playing the games i play @1080p maxed graphic options, on a 1060 strix and i would like to keep doing the same @ 2k if that means getting a 3080or a 6800x then thats what i intend to do, at native 2k, which should be just fine, and thanks to the shortage. i should have no problem getting a new card, once the prices hopefully fall back down to normal.
well, NO games i play support DLSS. so again, a moot point. only WOW supports RT, and its pretty minimal, again moot point. the rest of the games i play dont support RT, so chances are, if the radeon 6000s are less then the rtx cards, i will be getting one of the radeons. getting a 6800XT MIGHT allow me to play supreme commander at max graphics all the time, and not have to turn any thing down., the games recommended vid card is a 6800, and it still slows down quite a bit with the 1060strix i currently have, and always has with the vid cards i have used since the game came out, even after cpu upgrades, so its definitely the vid card
