Summary: I really like my the Gigabyte Z77X-UD3H. I received revision 1.2 which is the latest version from Gigabyte which is good as it had the latest bios already installed. Gigabyte has a little sticker on two usb ports which were different from the standard location of where one would normally plug in the keyboard and mouse. I used the ones suggested by Gigabyte to install windows 7 without any issue.
Pros: Good quality
Cons: wish all sata ports were sata 3 and had 2 more internal sata ports
Summary: Bought to replace a defective motherboard, i do the job well. Overclocking is easy, voltage are stable. The new UEFI BIOS is realy well made and intuitive. It also boot fast (no long device checking at POST, it go in 2-3 sec directly to OS boot.) The VIA onboard audio is good. The software is very simple but the sound quality is way better than the Realtek AL889 on my old motherboard.
Pros: Good quality onboard audio, 6 Sata port, Power, reset and clear cmos button. 3 full lengh PCI-E, Intuitive CMOS
Cons: Software in windows are useless, no linux drivers on cd
Summary: Great board for the price. Lots of higher end features and only skimps on stuff not as many people need. I wish it had more than 6 USB ports on the back, my old board it replaced had 8 and I have a lot of junk hooked up back there. Also only one USB 3 header inside and my case uses 2. Neither of those are deal breakers though.
Summary: I like Gigabyte motherboards and the Z77 is a solid product for the price. The only issue i have is the limited SATA 3 connection on board - I have a SATA3 SSD for my OS, and two SATA3 HDD for programs and storage. Not that you will notice the one in SATA 2 mode but.....
