Can my pc handle 2k gaming?

For my entire life i've played at 1080p but recently I've been thinking about taking the leap of faith to 2k, I just dont know if my rig is powerful enough for modern games to run well:

I'm running:
4070 ti super
ryzen 7 7800x3d
samsung 990pro 2tb
Gigabyte B650 GAMING X AX V2
32GB DDR5 6000MHz

What kind of frames can I expect? and do you think the upgrade will be big?
The monitor I was thinking of is 27" Odyssey OLED G6 G60SD QHD 360Hz
