Here are some of the first pictures of GIGABYTE's Aorus branded Z370 series motherboards. The lineup begins with the Aorus Z370 Gaming 3 and Aorus Z370 Gaming K3. These two boards are nearly identical to each other, and differ with only their onboard gigabit Ethernet controller, with the Gaming K3 featuring the latest Killer E2500 controller, while the Gaming 3 features Intel i219-V. Both boards feature just the one PCI-Express 3.0 x16 slot wired to the CPU, with the second slot being electrical x4 and wired to the PCH. GIGABYTE has been traditionally generous with its onboard audio solutions, and these boards are no exception. You get a Realtek ALC1220 (120 dBA SNR) CODEC strapped to a single headphones amp circuit, ground-layer isolation, and audio-grade capacitors.

Moving slightly up the ladder is the Aorus Z370 Ultra Gaming, pictured below. You get a similar CPU VRM implementation to the Gaming K3, but with two PCI-Express 3.0 x16 slots (x8/x8 with both populated) wired to the CPU, for multi-GPU setups. You also get a stylish I/O shroud. Positioned above the Ultra Gaming, is the Aorus Z370 Gaming 5. This board features a stronger CPU VRM, three M.2 slots as opposed to two on the Ultra Gaming, a higher grade onboard audio with a high-grade OPAMP, more USB 3.1 ports, 802.11 ac + Bluetooth WLAN; and a full-length I/O shroud. Leading the pack (for now) is the Aorus Z370 Gaming 7. Positioned further above the Gaming 5, this board features the highest-grade onboard audio solution from GIGABYTE, with an ESS Sabre AMP; M.2 SSD heatsinks, two gigabit Ethernet interfaces (Intel + Killer), and reinforcement braces around even more slots. These boards are expected to launch on the 5th of October, 2017.
