The ASRock Gaming K4 X370 represents good value for money and has performance numbers to back it up. Whether or not you are looking to jump on the Ryzen boat and join in with the many others who are tired of constant socket changes that Intel brings...

The Gaming Professional edition X370 is the premium enthusiast product, nothing less. Expensive? Yes, and yes, you will probably need a few firmware updates in the future. But it is one of the very few boards out there where I find the cost justified for what it offers in return regarding features. Nice job ASRock!
