It may be a little late to the party, but Gigabyte has just introduced a motherboard based on Nvidia's nForce 680i SLI chipset. Unlike 680i SLI offerings from the likes of eVGA and Biostar, the snappily named GA-N680SLI-DQ6 isn't a rebadged Nvidia reference design. Instead, Gigabyte has gone its own way, most visibly by installing a copper, heat pipe-based cooler that extends from the chipset to the power regulation circuitry. The board's layout is somewhat different from the reference design we tested last year, too. Gigabyte has swapped one of the PCI Express x1 slots for a 32-bit PCI slot and raised the SATA port total from six to 10. Gigabyte says the GA-N680SLI-DQ6 has four eSATA ports, but those aren't on the rear port cluster, so they likely come in an expansion slot bracket. The port cluster does include a whopping four Gigabit Ethernet ports, however. Gigabyte says those can be combined into two 2Gbps connections, should you somehow need the extra bandwidth.
