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: 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've read similar reviews about the onboard sound cutting out and/or dying but no issues with the sound on my board thus far.
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 and have run this mobo daily for about 16 hrs/day for over 18 months without a hitch. Running Win7 and 8.1 with 16 gigs of ram. Solid board and will still use it but I've woken up after 20 years of PCs and finally got a Mac.
Summary: I purchased one of these boards along with the 3570k in July 2012 and it worked fine for about 2 weeks. The audio eventually gave out and the board needed to be RMA'd. I got the new board directly from Biostar in city of industry, but that boards audio was delivering static and was also RMA'd.
