I have the older Asus A8R-MVP mobo and it's real good.
It's quite the overclocker, even if it does have a slightly quirky bios.
Took me a while to get the hang of it's oddness. Also took me a while to find the memory settings screen, which is kinda hidden.
I'm not the only one though, I've read many reviews which state that there are no memory settings available whatsoever! Doh!
