Pretty much any board that allows OC can do 4Ghz with everything on Auto for a 2500k or 2600k... 4Ghz is a pretty mild OC for these CPUs.
ASRock Extreme 4 is a good choice for around $150~160.
You'd better give people an idea of your budget when you ask for component recommendations.
thought i did also mentioned the desired budget bro, said i planned to have a $130 mobo but im unsure now
if so many ppl prefer having a P67 maybe thats what im gonna get then, just get the regular version, asus P8P67 or whatever it is called, think it will serve me just fine since i dont even know what i can do with extra stuff in fancier versions of the board
suppose ill go for the coolermaster hyper 212 as my cooler, cheap and efficient, might not be in stock though, looks kinda popular
will 650W be sufficient?? coolermaster.cosair psu?
