cant go wrong with the abit, imho its one of the best ocing boards available
got a soltek frn2l as well, allows higher vdd adjustment, but you can only get vdimm up to 2.8, and you can get 3 out of the abit due to it overvolting the vdimm
dfi seems like a safe bet as well, but i havent ever tried one of those so i wouldnt put my name to one
