Vortez tried the MSI X370 SLI PLUS
A quote from the article:
The X370 SLI PLUS comes out as a sleek, blacked out motherboard with all the primary benefits of the X370 chipset, including a host of the latest USB standards, robust heatsinks, high grade components, robust electro-static defences including the use of 'Steel Armour', and of course the high-speed M.2 32Gb/s slot. The primary and secondary PCIe x16 lanes are each given a triple slot clearance to give users optimal positioning so content creators (and of course, gamers) can get the best out of the use of a multi-graphics card setup.MSI X370 SLI PLUS Review @ Vortez
