When I was looking for a board, I found that the comparison tool on the Gigabyte site was very helpful. I soon realized that there are "clusters" of similar boards that are basically the same but vary for certain details. The comparison tool makes it possible to list side-by-side all the specs of several boards you might be interested in. In a particular "cluster" most of the specs are identical but the number of USB 2, 3 and 3.1 slots vary, occasionally the number of PCIe slots vary, the on-board audio may be different, number of SATA connections may vary and the number and type of video outputs vary. The latter may not be important if you plan to use an add-on GPU but is crucial if you plan to use the CPU's on-board video. The gaming boards usually have led lights with user-configurable colors. That is important if you have a windowed case and want the inside to look like Mr. Spock's work station on the USS Enterprise. By making a detailed comparison, you can find the best board for your needs and within your budget.
In the June buyer's guide, the most recommended boards for Customac Pro are NOT gaming boards. And in the full list of the listed Gigabyte recommended boards, less than half are designated as "gaming" variants.
This is a bit like buying a new car. If your heart is set on a Ford Focus, there may be 3 or 4 models that are basically the same car but with more (and more expensive) bells and whistles.
