This offering is from the Ultra durable 3 line up, so one of Gigabyte’s more budget-friendly ranges. All of these motherboards support DDR4 RAM only as opposed to 2x DDR3 DIMM and 2x DDR4 DIMM; which is a much better idea. They all also support the new M.2 standard for SSD’s and offer two-way Crossfire/ SLi graphics card support. Along with those features, they will all feature the standard Gigabyte motherboard offerings such as UEFI BIOS and the rest of the Gigabyte software.
The GA-Z170M-D3H looks pretty nice: two USB 3.0 headers, right-angle Sata, M.2 out from under the video card, but why not one but two PCI slots?!
