i have that exact board
the board has tons of overclocking options. acc works good. asus site gives out alot of bios updates. my windows boot ups are faster with this board. the hd 3300 is actually a beast when oc'd. the 8+1 power phase seems to help out my cpu temps and keeps it stable when applying higher voltages. the board has 3 case fan 3 pin power connectors.
the hd 3300 core overclocks easily to 950mhz. i have it at 1100mhz with NB voltage 1.40 6C game load mobo temp change.
