please disregard above "really quite bad" review. It's for an ever so slightly differently named motherboard! I'm sure this one is fluffy and brings you breakfast in the morning!

4* So Far So Good

Easy to live with layout,nice easy to deal with bios which i found quite intuitive, although be warned the board is full atx in length but slimmer in width so standoff layout doesnt really support mobo at 24 pin connector area very well. i do have an issue with usb disconnect noise on wakeup from sleep, all mobo drivers are installed and flashed bios to latest version, all to no avail with the usb issue. so if anyone knows a fix to that id appreciate it ! :)
1* really quite bad

Nothing but trouble and bad performance from this board and judging from forum posts i found, it wasn't just a one off for all the following problems on the one i had.

Massive trouble with the usb ports not powering up or identifying peripherals on boot up (there was about a 50/50 chance my keyboard would be identified to be able to get into the bios for example)

The onboard sound chip is dreadful. Pops before playing every windows desktop sound.
EVERY video i played whether a file on the hard drive played in ANY media player or youtube videos, the sound was dreadfully out of sync.

The board looks great on paper but it's the worst motherboard i've ever used (and i've used lots). Stay away from the current generation Gigabyte boards that use VIA chips for sound and usb is all i can advise.
