Im getting a new MOBO
i dont know whether i should buy the GA-Z77X-UD3H and use it with my asus sound card .... or just get the GA-Z77X-UD5H cuz several people said that its onboard sound card is pretty good
Obvious disclaimer aside from my signature, there was a study done recently that showed that sound cards tend to produce better quality sound than integrated chipsets.
If you already have a Xonar, and you care about getting the best audio quality, then I'd say go for it. If you're not as concerned about audio quality, then save a PCI slot and go with the onboard sound.
