In my main PC, I have an ASUS ROG STRIX 5700 XT OC EDITION 8G. I'm currently tweaking it via powerplay tables, to get more performance. So far it currently matches the 2080 super in performance and can do 4k 60+fps ultra. And in my second pc, I have my old MSI GTX 970 GAMING 4G. I VBIOS modded this one too, running 1580Mhz core and 4110Mhz memory @1.312mv with power limits removed. With these settings, it can do 4k medium/high at 30 to 40 fps and depending on the game, sometimes 50-60. At 1440p, it'll easily achieve 60+fps at ultra.
