With Ryzen 3000 series (Zen 2) right around the corner people are getting excited and prepping for upgrading their systems.  After all one of the big selling features of the AM4 platform was longevity in support, none of that two gens and you’re out business but a promise to support the socket through 2020.  This was one of the leading reasons I moved my personal workstation to the Ryzen platform with the Ryzen 7 1700 and a spent a bit extra on my motherboard and went with the ASUS ROG Crosshair VI Hero.  Another option in that price range and the board we used for our ongoing testing was the very capable MSI X370 Xpower Gaming Titanium.

The MSI X370 Xpower Gaming Titanium was one of the most excitable boards leading up to the launch of the Ryzen platform thanks to MSI and their joy of showing it off at events, I even got a chance to get hands on with it at my first visit to CES in 2017.  But, thanks to a reddit post getting a lot of attention thanks to various outlets there is a sweeping assumption that owners of MSI 300 series AM4 motherboards are going to be left out in the cold.
