A quote from the article:
We test the Gigabyte X99-Ultra Gaming with the latest Intel 20-core Broadwell-E processor. This new motherboard comes with both Intel and KillerNIC LAN, U.2 and M.2 drive support, USB 3.1 Type-C, and audio-tailored for gaming. It also supports multiple videocards and to look pretty it provides fantastic LED lighting.Gigabyte X99-Ultra Gaming (with Broadwell-E) @ techPowerUp
