Overclocking is going to be CPU-dependent so there’s nothing to worry about there. If your CPU overclocks well then this board will be perfectly capable of maxing out your chip. Remember that the Haswell CPUs are largely controlled “on-die”, motherboards only have the ability to condition and filter the input power. That said like with all ASUS Z97 motherboards the digital VRM and the high quality 8 phase design means overclocking is supported by clean and stable power. But more importantly the BIOS makes overclocking really easy and if you’re “not that way inclined” with overclocking then ASUS offer automatic overclocking utilities in the BIOS to do the hard work for you.
