After taking a look at ASRock's extremely well equipped X370 Taichi earlier this month today I will give ASRock's Fatal1ty X370 Gaming K4 a close examination. The two motherboards have similar features, but the Taichi is priced higher because it carries some more features than the X370 Gaming K4. Today I will see exactly what the differences between the two motherboards are, and if it's worth saving or spending.
