Thunderbolt 2 is barely a real thing yet, but that hasn't stopped ASUS rolling out the first product on the market to use the interface. Now, you can buy a motherboard that sports the super-fast data link.
The Z87-Deluxe/Quad ATX motherboard is the first to offer Thunderbolt 2, which combines four 10Gbps Thunderbolt channels into two bi-directional 20Gbps Thunderbolt 2 ports. If you're interested, that's four times faster than USB 3.0 — enough to drive two 4K displays at once.
Otherwise, the 'board is fairly standard, high-end stuff: it features Haswell CPU support, 10 SATA-6 ports, 8 USB 3.0 ports, and 3 PCIe 3.0/2.0 x 16 slots. There's currently no word on availability or pricing — but expect it to be fairly expensive. [Anandtech]
