$800-900? The 10GB AIB variants already go for $700-850. By doubling the VRAM I doubt you'll see them for less than $1000.3080 20GB will likely be the best-balanced choice in the $800-900 range this generation. That said, I'd rather save a few hundred (my guess is Navi 21 will cost $600) for 10% less performance (again, a guess where I think Navi 21 will land vs. 3080). That $200 will pay for a new Ryzen 4600 and part of a new mobo to support it.
