Also got an EVGA 3090 FTW3 UG @stock and played for 2 hours to New World yesterday evening. Haven't checked the GPU temperature but my girlfriend told me the room was pretty hot. No particular issue except some rare fps drops but now I'm quite reluctant to re-launch the game ...
My config if it may help : Asus Crosshair VIII Dark Hero, Ryzen R9 5950x@stock, 64 Go Gskill TridentZ 3200/C14, 2 x 1To - Samsung 980 Pro, 2 x 2To - Crucial MX500, PSU: EVGA SuperNova 1200 P2. I haven't updated the lastest Nvidia drivers yet (it may be important).
EDIT : I also waited for 1 hour on the queue screen !
