beast of a board! I own the Unify X570 which is an amazing board already but this is just a straight incremental upgrade over it. B550 Unify vs X570 Unify 4x M.2 slots that only take away SATA lanes 3x 4.0 + 1x 3.0 - VS - 3x 4.0 M.2 slots 14+2 x 90W phase VRM - VS - 12+2 x 60A VRM 2 dimm options - VS - Only 4 dimm option Full SATA performance on B550 chipsets - Gimped SATA performance on (all) X570 chipsets What's there not to love?
