The Maximus IX Formula is the latest top-tier ASUS Republic of Gamers motherboard for Intel's new Kaby Lake CPUs and Z270 chipset. While below the Maximus IX Extreme in the ROG product hierarchy, the Formula is likely to be more popular as it targets a lower price, has a more customisable aesthetic and more features that are usable to the average PC builder, rather than an extreme overclocking audience.
