dfi lanparty NF4-ultra d BEST overclocker and good general stability one problem is that they effectivly have only 2 ram slots (im quite sure the yellow ones) as the other 2 kill ram or don't run it at high enough speed
the MSI is a good board and it can oc quite well havn't heard of many bugs in it but msi is natoriouse for new buts in l8er revisions
don't get an asus cos they are horrible (srry dude) they have terrible voltage controll e.g. when set to 1.55vcore it goes between 1.5-1.6 and that is HUGE. they are quirky when it comes to ram, the old versions have horrible chipset fans (mine has died after 6 months)
