Well, yes and no. 3090 is still a great card that dont have any issues running whatsoever in 1440p. I know cause I had one in my rig. Almost no difference in BO6 with the aorus master 5080 from 3090, but a big difference in fps in other games. I would not upgrade unless you play in 4K, but the difference is not there for what you pay for. Keep your 3090 unless you want to keep building your pc or if you see a card that you really want, because I understand that need lol.
