Upgrading every single GPU gen will never give you big results (assuming like for like, so 2080 to 3080 for example, not 2060 to 3080). And at the same time, your card isn't redundant once a newer gen is released, especially when you're running an xx80 variant.
I'd wait to see how games perform for you. There's no need to upgrade instantly, and since you have access to DLSS 2.0 already you probably won't struggle with titles like Cyberpunk on a 2080. And if you do feel like the performance isn't good enough for whatever reason, then look into an upgrade. Personally, I try to skip every other gen. Currently on a 1070 and planning a jump to a 3080 this month. That's when the purchase feels really good, and not "do I really need this..?"
