EDIT: A few days ago I bought a HP X34. It's a 3440x1440 ultrawide with 165Hz refresh rate. Obviously my setup can't hit constant 165fps in all games, but I'm comfortably getting 100+ in most games, 120+ in Forza Horizon 5 or Doom Eternal. Can't complain :)

I'm looking to buy a new monitor, making a switch from two 16:9 to a single 21:9. Everywhere I read the opinions are that on an ultra wide it doesn't make sense to go lower than 1440p, which I guess holds true for 34" monitors.

However, I'm worried my 3060 Ti won't be enough for that many pixels. Right now I'm enjoying uninterrupted framerates playing at 1920x1080.

How much should I really worry about making this switch? My other option is to go for a 2560x1080 monitor that's smaller (29").
