For now, let's talk more about the motherboards we just tested. The king of the B660 performance hill (without going stupid on pricing) is the MSI B660 Tomahawk Wi-Fi as it performed exceptionally well in our testing. The MSI Mortar is a great mATX option, too, as is the Gigabyte B660M Aorus Pro AX.
MSI has dominated with B660 which is good to see because they're taking VRM performance seriously.
[blue]We should note, if you're only interested in running something like the Core i5-12400 (or slower) and have no plans to upgrade, then VRM performance is a non-issue and not something you need to worry about.[/blue]
