The TUF series of ASUS boards are recognizable thanks to the Thermal Armour which covers the vast majority of the board and are marketed as having mil-spec components to outlast other motherboards using the same chipset.  This board supports quad GPU setups but keep in mind that there is also an M.2 port, that you need a more expensive CPU and the fact that there are only three PCIe 16x 3.0 slots, the other card will be in a PCIe 4x 2.0 slot, leaving a single 1x slot for other cards. The AI Suite III overclocking software is not supported on this TUF board but [H]ard|OCP had great success overclocking manually, some of their reviewers more so than others though.  Check out the full review if you are comparison shopping for an X99 motherboard.
