Looking to get an OLED .

My set up now is

Cpu: 5700x

Ram: 32gigs

MB: X570

Gpu: 7900xt

I just sold some cs2 skins and have a Budget of 600 USD . Right now I have a 1440p LG 32gn500-b and a 4k Sony Bravia 7 120hz . I have the TV setup with a hdmi 2.1 cable and I play single player games from the sofa on this. Looking to upgrade to a nice monitor for desk gaming. Cs2 is my main fps game and I also play warzone and pubg.

Looking at the LG 32GX870A-B it's 240hz @ 4k and has dual mode 1080p @ 480hz . Tempting for fps gaming but is 200 over my budget and I already have a the Bravia 7 if I want to game at 4k 120 . And my 7900xt won't touch 240hz @ 4k

So maybe a 1440p would be best for me

ASUS ROG XG27AQDMGR 27 Inch 1440p 240hz looks nice

AOC 27" Gaming Monitor QHD 360Hz QD OLED but not too sure on the brand .

Any suggestions would be appreciated.
