Why not Asus they are wicked overclockers. The DFI lanparty boards are very good and come with a passive/active (if you add the fan) northbridge cooler which allows good overvolting the NB. Bare in mind though it is big and may well get in the way of some of the larger
cpu air coolers such as the noctua.
DDRIII or DDR II though? If its DDRIII then maybe the Foxconn black ops(very expensive but its sweet) or the Abit Hotfoot may be worth a looksee
bare in mind we are only 4 months off Nehalem though
