In part one of our review of the Gigabyte Z87-UD3H we looked at the design, features and layout of the board. Now in part two we are going to see if those choices were good or bad. Gigabyte has a fairly good history of designing boards that have great performance, but as have also seen boards that fall apart as soon as you push them (overclocking). So far it looks like the Z87X-UD3H has the right components and design to maintain performance for both stock use and also for overclocking. Let’s put that theory to the test shall we?
