i see some appeal to DLSS and high refresh displays
I don't and I'll tell you why. nVidia has said that DLSS adds a constant amount of time to the rendering of every frame which gets worse at higher resolutions. At 4k and 70FPS, that's easily 20% of the frame time for DLSS alone. DLSS does not work well when you want really high frame rates, it works well when you're trying to hit 60FPS, not so much for 120+. The tensor cores only run so fast and at higher frame rates, that becomes the bottleneck. There is a balance to be struck between the time spent rendering the scene and time spent on DLSS which depends on the capability of the card.
