Our selection of motherboards were all available on release, however, we have now updated each to the latest available BIOS so we can objectively look at their performance and features to see which would be best for you and your requirements. The motherboards we'll be looking at are: ASRock X370 Taichi, ASUS ROG Crosshair VI Hero, GIGABYTE AX370-Gaming K7, and the MSI X370 XPOWER GAMING TITANIUM.
