ITreviewed posted a review on the Gigabyte GA-EX58-EXTREME

Gigabyte's GA-EX58-EXTREME is not for the fainthearted. This motherboard is designed for extreme users wanting to break speed records. With friendly overclocking features such as Precision OV (Hardware Overvoltage Control IC), Debug LED and onboard clear CMOS switches, along with comprehensive BIOS options for reaching higher limits with more detailed settings, including CPU frequency stepping, Over Voltage increments, memory multipliers and advanced memory timing controls, it's no easier than ever to tweak your system. And just when you thought two PCI-E x16 was good enough, Gigabyte delivers three, with support for both three-way ATI CrossFireX and three-way nVidia SLI, enabling powerful graphics configurations for extreme multi-GPU gaming. It's not all pain sailing, however. The GA-EX58-EXTREME is an expensive motherboard solution and the BIOS is probably too complicated for novice overclockers. There is no SLI bridge component included in the kit either, and there is no Serial Attached SCSI (SAS) onboard support. But if you are looking for a top-class product that offers premium performance for Intel Core i7 platforms and probably the most extensive range of features ever seen on a motherboard, the GA-EX58-EXTREME would make a great choice.
