Summary: Ordered as a temporary replacement for a GigaByte Z77X-UD5H while it was being repaired after lighting came in thru phone and internal modem. Worked great, wish it had more Sata-6 ports. But for the price it was great.
Summary: Worked really nicely in my case, but unfortunately it arrived DOA, so I bought an MSI instead. This seems to have had all the features I was looking for, and a nice quality build, but like I said unfortunately, it never actually worked.
Summary: Purchased new from Micro Center May 2012 in a combo deal with the i5 3570K and it's been a rock solid combo up until maybe a week ago.

I got the new board directly from Biostar in city of industry, but that boards audio was delivering static and was also RMA'd. Now on the 3rd board i am back to no audio at all. It appears the Biostar Tz77a has bad audio chips. Biostar's quality control on it's new and refurb products appears to be poor.
