Xbox exclusives are going to be playable on PC so there’s zero reason to buy an XboxI've got one on pre order. I'd be more excited if there were more games coming out for it. As it is any real graphical optimizations for games for the system aren't coming until 2021.
I would like to build a new PC in 2021 as well when more of the latest cards become available. I'm looking forward to seeing how Big Navi compares to the 3080.
