Gigabyte as well launched several X79 motherboards like the G1.asassin, the UD3, UD5 and sure .. the UD7. That last one we'll be looking at today. A very complete motherboard I must say, with all kinds of gadgets and fresh looks. You will see four PCI Express x16 slots, the rest of the expansion options available in the X79-UD7 include three PCIe x1 slots, four SATA 3Gbps ports, as well as a good six SATA 6Gbps ports. The rear I/O bracket shows a pair of USB 3.0 ports and 7.1-channel audio with digital S/PDIF out, but also a special OC button, a CMOS reset switch and much more.
