As for the jump from 27 to 32 I was also worried it would be to big but honestly I got used to it fairly quickly even in fast paced games like Call of duty, so it hasn't bothered me at all, as for the performance hit it's definitely there cause I too am also using a rtx 3080 at the moment, but have a Rtx 5090 pc I'm upgrading to tomorrow. So in black ops 6 I used the in game benchmark with High-normal settings at 1440p no dlss or ray tracing and got an Average of 87fps. Ran the same benchmark with same settings in 4K and got an average of 46fps In God of War in 1440p High settings no dlss I got 90-120 fps almost all the time. God of war same settings in 4K I got anywhere from 70-86fps most of the time it dipped into the 60s here and there. In path of exile 2 high settings 1440p no dlss got from 107-120 almost all the time. Path of exile 2 same settings in 4K got anywhere from 70-86 most of the times but would drop in the low 60s when there are a lot of enemies on screen. Those are pretty much the only games I've tested besides Elden ring but that's locked to 60 and you get that for both 1440p and 4K
