Personal the Asus Crosshair is more bang for your buck. I got one and it keeps really cool when gaming (due to its large heatsink) and is very easy to overclock your CPU.
The Sabertooth is good but I really do like the Asus Crosshair.
Sweet, I do like the Formula-Z looks so good.
Thanks guys, I have made my decision. I a, going to purchase the Asus Formula-Z
