There isn't a compatible motherboard for Zen3 that supports Zen4.

Zen4 will probably need a different connector and support DDR5 unless you go back to older tech, which might not be available for another two years.
I'm still using a 4770k with an OC of 4.2ghz, which isn't too bad. I'm planning to upgrade this year and want a motherboard that can last 4-5 years so I can upgrade at least one generation. It's frustrating because I'm upgrading at the end of its life, but it's what I have to do.
Choosing the 3080 fits your setup perfectly. I’m using it on a 1440p, 144Hz display, which should be sufficient right now—I currently have a 1080p model.
