"Motherboard chipsets haven’t really changed much in the last few years. There’s been some support for new storage options and standards, like M.2 for SSDs, some limited support for features like Thunderbolt, and faster memory speeds have trickled out over time. Intel might shake things up a bit for its 300-series chipsets in 2017, if rumors are to be believed, with integrated support for Wi-Fi and USB 3.1.
Both standards could be useful to consumers and a new report from Digitimes implies Intel is considering the concept. USB 3.1 Gen 2 offers up to 10Gbps of transfer speed, while USB 3.0 (aka USB 3.1 Gen 1) tops out at just 5Gbps. Objectively, there aren’t that many consumers who currently need USB 3.1 Gen 2, but the technology could be useful for secondary displays or high-performance external storage arrays."
About the only thing missing is 10GBASE-T Ethernet on the motherboard to perk up physical network performance.
USB 3.0 is backwards compatible but USB 3.1 now adds a new incompatible C connector that will take time for chassis vendors to deal with. Most likely a pair of USB 3.0 ports and a single USB 3.1 port until new chipsets with more ports become available.
I use PCI Express Wi-Fi cards with my boards now, they work fine. The ones I have now are older n300 and newer models now have ac1750. PCI Express x1 slots maike sense for Wi-FI as the technology is still evolving relatively quickly.
