We keep on testing new LGA1366 mainboards based on the Intel X58 Express chipset. It would be too much to call them a second generation because they are not fundamentally different from the older ones, but they can indeed be viewed as a second wave of such products. There are two reasons to the release of the new mainboards. First of all, products introduced together with the LGA1366 platform itself have already become outdated. There have been numerous improvements in mainboard making over this time, so improved product revisions are indeed necessary. And second, modern high-performance mainboards have to be equipped with USB 3.0 and SATA 6 Gbps interfaces. We already reviewed Gigabyte’s flagship GA-X58A-UD9 and later took a look at ASUS’s highly promising P6X58D-E. Today, we are going to check out the Gigabyte GA-X58A-UD5 (rev. 2.0) model.
