The ASUS Z170 Deluxe was our other standout performer. It was at its best in our overclocking tests, where the board was able to maintain the highest BCLK value and also the highest overclock. The more the BCLK value deviates from the default, the less stable the system is, and this speaks volumes to the quality of the board's components. In addition, the ASUS board placed within the top three of most of our benchmarks. In terms of official multi-GPU support, it supports up to NVIDIA quad-GPU SLI. It also comes with dual Intel Gigabit LAN, albeit without support for teaming, and its PCIe slots are sensibly spaced to accommodate dual graphics setups. Furthermore, it was the only board to feature onboard Wi-Fi support with the 3x3 module, definitely a welcome feature for anyone who doesn't have the luxury of setting up their system near to their router.
