Intel X38 chipset - Gigabyte X38-DQ6 motherboard Review
Though it might get lost in the hustle that is the Intel X38 chipset launch, the Gigabyte X38-DQ6 motherboard turned out to be a GREAT motherboard in my testing. The features were superb with the inclusion of multi-GPU PCIe x16 slots, eight total SATA ports and an external connection configuration that is unique and actually very useful. The performance of the motherboard was faster than its competing P35-chipset boards and the overclocking potential that the board showed exceeded my expectations and set a new record as well.
