This card was the smart buy for 4k out of the Super lineup. One can count on one hand the number of games which might require outputting to 1944p or 1800p instead, resolutions which are a still a big step up from 1440p.
my rx7800xt nitrox + giving same performance with overclocked gpu clock 2680mhz, slight high power draw 290w, way cheaper that your gpu. i am having better low fps though.
