Hardware purchase help

I want to upgrade from the 3060 to rx 7900 xt or maybe xtx if i save up some more (mainly with the intention of playing vr at higher graphics settings)

But i can’t decide between new card or buying a nice oled monitor

My current specs are 3060 12gb vram ryzen 9 5900x 32 gigs of ddr4 3200 mhz with the game installed on m.2 drive

my main questions are In general how much better will dcs run both in and out of vr with the 7900 xt/xtx over a 3060?

And what are peoples experiences of switching from cheapie gaming monitor to oled with dcs as the main focus ?

note: i understand it isn’t really a dcs specific question especially with the monitor, but it’s like the only game i play so it made sense to me to post here sorry.
