HardwareLogic posted a review on the Gigabyte GA-EX58-UD4P Motherboard

At about $260 street, Gigabyte's EX58-UD4P sits somewhere in the middle of the X58 pack, but that's only when looking at the sticker price. A glance at the spec sheet reveals anything but a mid-range motherboard, and this one tilts heavily towards the high end. In fact, all that really separates the UD4P from Gigabyte's pricier X58 models are two more SATA ports, an additional LAN port, and slightly improved cooling, positioning the UD4P at the cutoff point before diminishing returns kicks in. But while the UD4P offers best-in-class features at a mid-range price (by X58 standards), will it follow suit with best-in-class performance?
