Maximus 6 Hero.
I think in global ROG make better boards than GIGABYTE.
Softwares are better, probably and voltage are more stable, more settings.
People love that different ROG softwares, I don't know between ASUS and GIGABYTE I have more confidence in ASUS hardware.
That doesn't mean all ASUS boards are better than any GIGABYTE.
But last 5 years ASUS is motherboard leader.
Look only Rampage 4 Extreme, I think that motherboard and 4770K to install inside will boot up.

That's biggest mistake probably in my life because I didn't start with 3930K immediately in October/November 2011. I would laugh to this Haswell comedy and upgrade on IB-E for 150$. Second mistake is when I bought ASUS GTX580 DirectCU II instead of
580 Classified monster.
