Hi guys. I am building a HTPC using assassin's guide - I did this last year for my father and I've built quite a few other rigs for myeslf (for other uses). I am doing an Ivy Bridge Build, and want to stick with Gigabyte for the motherboard because of personal preference. So based on assassin's guide, I'm looking at the following boards:

GIGABYTE GA-B75M-D3H

GIGABYTE GA-H77M-D3H

The H77 has a few extra Sata 6.0 Gb ports and more USB 2.0 ports, and small perks like that. None of that really matters for my build. The one difference between the boards I noticed was the audio chipsets. The B75 uses a Realtek ALC887 chipset, while the H77 uses a VIA VT2021 chipset. I am wondering what the difference is in the audio chipsets. Is one notably superior to the other? I know I am probably being way too anal for a casual user like myself, but I like to be thorough. The price difference of 20$ is not really important, if one chipset is better than the other.

Other info: The rig will be used primarily for HD and SD media (tv shows and movies), and secondarily for music and light web browsing.

Thanks in advance!

Are you sending audio to AVR by hdmi ?

If so... Well ...

As Mfusick hinted no difference if you are bitstreaming to a AV receiver.

Yes, I left that out. Audio and video to be sent to AVR via HDMI. Ok thanks guys, I'll probably just go with the cheaper board then, since there are no features on the H77 that I need. Appreciate the quick responses!

I have a follow-up question. If for now I was relying on HDMI out to a TV but DTS and DD audio tracks out over optical to my speaker set / decoder, would the Via on that board be worse than the Realtek? Or indistinguishable?

P.S. I Know the b75 board he linked to doesn't have optical out, it's a general question regarding the two audio chipsets if you are using the optical out on competing boards.

Indistinguishable. DTS and DD are compressed formats, neither chip can alter them.

Just making sure, thanks! smile.gif Been a long time since I've seen other than a Realtek chip for onboard audio.
