Someone was asking about the sound quality of the board.
I found this at bit-tech's review;
Finally, we get to the audio numbers and we have to say they we thought something was wrong here. The results are practically off the chart and akin to a decent discrete sound card. All three of our RightMark benchmarks pointed at a highly capable audio processor - in fact, the results were so impressive that we reinstalled Windows and tried various different settings to check our results weren't flawed. This isn't totally unsurprising, though; while both of Gigabyte's previous X99 efforts we've looked at were medeocre when it came to audio, the GA-Z97N-Gaming 5 still holds the top spot for overall audio performance in our Z97-based testing.
