Question Will New GPU Get 4K On Arma at 60+ fps?

[EricLane]

I ordered XFX Speedster MERC310 AMD Radeon RX 7900XT Ultra Gaming Graphics Card with 20GB GDDR6, AMD RDNA 3 RX-79TMERCU9

I also just ordered GIGABYTE M32U 32" 4K 144Hz Gaming Monitor with IPS, 1ms Response Time, HDMI 2.1, USB 3.0 - Black

This is an upgrade from my current 1440 27" 60Hz monitor.

I am hoping to play Arma Reforger and Arma 3 at 4k. But I am worried the new GPU cannot handle 4k and I'll be stuck on a 32" 4k monitor playing at 1440. Grok says this would look worse than native 1440 on my current 27" 1440. Am I likely to get a reliable 4k 60+fps on Arma Reforger and Arma 3? Or should I cancel my monitor?
