Hard to say without testing the exact scene and render settings.
In any case, 2 3080s won't be twice as fast as 1 3080, that's for sure.
The 3090 also has the benefit of having more than twice the RAM, so if you are choosing what to buy, that might be a good reason to get the 3090.
Edit: Oh, you already have a 3080, just reread the original post.
