Yeesh why ask a question about a motherboard if you're going to be so fixed on what a couple of magazines write about.
The problems I had were compatibility issues...for whatever reason even though it had an nvidia chipset it did not want to work with my nvidia video card.....ASUS (in broken english) says my video card is bad...I get a MSI board with via chipset and it works like charm.
A lot of the people at the monthly LAN I go to have ASUS...problems with the SATA controllers acting up has arisen over more than just one person...this of course mainly applies once you start to get to overclocking.
However my main arguement besides my own personal experience and dislike for them is also the fact that tech support is utter crap, so I hope you'd never need to call them...
as for people who say 'well my motherboard works' Well I sure as hell hope that when the motherboard comes out of the box it works like it should...that's the whole **** point.
Those PC Magazines, all they do is pop in the board and see if it works....if another one wigs out or doesn't work it's considered worse and then by default the ASUS will be seen the best.
As far as overall useability, flexability and tech support combined, DFI is better
If you just want a plain board that should work right, and not have to tinker with then go ahead and get the ASUS and hope you NEVER need to contact their tech support.
