what is the problem with GA-Z77M-D3H (rev. 1.0) .... i don't hav big budget and ASRock Z77 Extreme4 is costly mobo....
Since u have great CPU for overclocking, than you would benefit from a this mobo as it have 8+4 power phases and its suited for OC better than the mATX sized mobo.
That website doesn't have that many choices, so if the price is the factor,
that Gigabyte mobo will have to do : )
