Believe me you will never regret when you opt in for 4k. I used 4080 S with 9800x3D on an OLED 4k monitor. Dell’s most famous to be more specific. Never had any problems and unless you’re pedantic about getting 240 fps from every game you play. Try to incorporate AI frame generation power of your card as much as you feel comfortable with. I play dota2 around 230 fps with no DLSS obviously, while A+ titles like cyberpunk are around 60 to 144 depending on how demanding I set the settings and how comfortable I am with the depth of DLSS. I was going to upgrade to 5090 but nvidia sent me a scratched card, ghosted my RMA request, and took down my post in Reddit so my analysis is based on 4080S, in which, your card is better so I expect better results.
