X870 looks like an easy pass for X670E owners. If the vendors decide to offer a bunch of features and PCIe slots under $300 I could see people being annoyed. I doubt that will happen though.
Shave off another $100+ and this would be good.
I've been sitting on a 1080ti for a while myself. Seems the stores and vendors piled up a few too many of the RX6000 cards.
The only board failure I remember having was due to a power surge. Seems like I've had it easy compared to a lot of other users. The only issues I've had with my X670E Taichi was needing to flash the BIOS and it will hang on memory training after a power outage. I need to set it to power off...
