You didn't see it either!
I saw your post. You have suggested one board and then linked a review article.
The review you have linked includes benchmarks for video encoding and the board you have suggested loses in every single benchmark to the Gigabyte board.
They gave the ASRock board a value award, which isn't surprising since they are one of the cheapest motherboard manufacturers.
The reality is that the performance differences they have shown are very small. The best board for any particular build will depend more on the features required and the applications for which it is used. There is also the argument of quality, which is why Asus are able to charge more for their boards.
