I decided to build new amd-based pc (no intels) so i cant decide which one MB should i choose from these two.. http://www.gigabyte.com/products/comparison/list.aspx?ck=2&pids=3891,4397 UD3 is cheaper and almost the same as UD5 but i dont know are they with the same performance or UD3 is with lower performance than UD5? (btw i want to put amd fx 8350 cpu)
