Audio Quality
We tested the onboard audio quality at 16 bits and 44.1 kHz to see how each codec handled this common standard.
The frequency response curve of the Intel solution appears to be altered by the built-in equalizer, even though we disabled advanced audio features for each test. All of the codecs drop off around 18kHz, but the DFI solution provides a slightly better range.
The noise level charts look messy, but every codec had a -110db noise level throughout most frequencies.
Dynamic Range looks good as well, but we don’t know what we could do with frequencies above 20000kHz if none of the codecs can play them at audible volume levels.
We see very little distortion in the sound signal of each onboard codec, except for an odd spike in the base range of Intel’s solution.

Where is the Cost/Performance ratio.
I think ASrock have done well to put forward a competitive offering and I reckon they will be notably cheaper. I think they bring the enthusiam to the masses.
I personally would go for the Gigabyte or DFI board, because their builds are quality and could conceivably last for years.
