We've seen many X58 motherboards since their initial launch, and lately some refreshes with SATA 6G and USB 3.0 coming to the market. But we've never seen a board with a price tag like the Gigabyte GA-X58-UD9. We are well aware of Gigabyte's reputation among overclockers, and truth be told, we're big fans as well, since we've seen them display some of the best stability and recovery from extreme overclocking we've ever encountered. But the UD9 is crazy expensive, so how do things shake out when we put the board on sub-zero cooling?
