AsRock extreme 4 overclocking

Solution
Of the two, I'd go with the Asus, the Z87-A is a great mobo, OCs well, handles DRAM well - Asus seems to have the best handle on the Z87 and Haswell
well if your like me and still use all your old hardware you may be left out with asus z87 . i still need and use rs-232 stuff and the best i can tell it not on any of there z87 boards. and no telling what else they renoved to come as a supprise when you go to hook things up. someone told me ''just go but a converter and buy a whatever'' but like i replyed back was why should i have to buy more stuff to support there board? why not go with a brand that has the headers and slots that my hardware needs for the same price or less then asus? you got to realy look the specs over good or it may cost you more later.
