I have a render farm for animation jobs, and all of my nodes are built with this board. Boots on the first time, every time and is easy to overclock. Love it.
I also just upgraded my main workstation with that board, and finally phased out all my ASUS crap. I can't say enough good things about Biostar. Zero problems so far, and all of the advertised features actually work.
