Upgrade 8700k?

I recently got a 3090 and im still running an 8700k at 4.7 GHz I was wondering if it would be worth it to upgrade to like a newer ryzen 5000 cpu or 11th gen when it comes out

I game at 3440x1400 200hz and im fine with anything over 80 fps which I get in basically everything so im just wondering if it would be worth it

all i do is gaming

Probably wait around for the 11th gen release and see some figures before making a decision. 8700K probably hold you over for a while.
