The new generation of AMD boards feature some interesting aesthetic choices, such you can see on ASRock's X470 Taichi Ultimate.  The black and grey theme is contrasted by the RGBs you already knew were present, but it is worth noting that TechPowerUp considered the implementation of the blinken lighten as exceptional.  Sadly the same could not be said of the audio chipset on the board, which they found lacklustre for a flagship model.  Their overclocking tests showed no deficiencies, the boards ability was met or exceeded the other X470 boards they have tried.

As it is a flagship motherboard, there are quite a few features to cover in the review, which you can find here.

"In addition to the new features brought to the X470 chipset, the Taichi Ultimate offers additional SATA ports, 10 gigabit Ethernet, and superior control in overclocking using the Hyper BCLK Engine II, just to name a few. ASRock's Taichi line of motherboards have traditionally been top performers. Can the ASRock X470 Taichi Ultimate and X470 chipset match up?"
