> 144Hz
That's your problem right there. Most people, myself included, are perfectly fine at 60Hz since we don't do competitive FPS gaming. At that refresh rate, my 2070 is perfectly happy to render games in 4k and I really don't notice any significant difference compared to 120Hz. If > 60Hz is really important to you, it's going to be another generation of video cards before single-card gaming can handle it well (probably the 3000 series cards will be capable).
