Go with the Big 3 - Asus, GB or the Rock, using full chipset, Z87, Z77, X79, P67...those will OC everything, but the main thing would be to decide on a CPU (if Intel and newer, a K model) and then check the mobos that have the appropriate socket, some of the lesser chipset may well OC well, some might not at all, with Intel if the mobo is limited to 1600 DRAM or lower then you don't want it...really need something to work with here for an intelligent answer, rather than the generics I'm laying out
