I just picked-up the Asrock B550 Taichi which is currently going for $219 (on sale from $300). I debated the x570 vs B550 chipset and decided that B550 met my needs. One of the less common features the B550 Taichi has for a B550 board is that the top two PCIE slots can both run at PCIE 4.0 (1x16 or 2x8) so it does offer an additional PCIE 4.0 pathway. I just don't know what I personally would use any of the additional PCIE4 lanes for with the X570 chipset. With the Taichi I could install my single GPU (will never have 2), one PCIE4 m2 drive on board, one PCIE3 m2 drive on board and still have a PCIE4 x8 and PCIE3 x16 slot available for future needs like adding another NVME drive with an adapter. Even at $219 I am aware that I am paying a bit of a premium for the Taichi, but that comes down the fact that I am willing to spend a little more for a good looking board. I looked at the ASUS ROG Strix B550-F also, but it didn't have an internal USB-C connector which I needed.
