To study the design and functionality of the mainstream and entry-level chipsets for the AMD Bulldozer platform we decided to go with two mainboards from Asus: Asus M5A99X EVO and Asus M5A97 EVO, based on AMD 990X and AMD 970 chipsets respectively. In our today’s review we are going to compare them against one another as well as against the previously tested mainboards on the top Socket AM3+ core logic set.
