Belial.. tbh most of us here on Head-Fi will find it difficult to help out with motherboard audio. We all look down on it for good reason (and we are not snobs no way): namely it's motherboard audio. To kick off, a motherboard that claims it can amp a 600 ohm headphone is quite frankly laughable - no offence. it's not going to happen.
Also the DAC's used are difficult to pin down quality wise.. so many variations....... maybe one day they will be really good, but not now. I've tested out a great set of headphones on one the best of mobos (SupremeFX)... and no... sorry.. not good.
