I have both boards too (ASUS a8n-sli and DFI lanparty ut sli-d) and the dfi is much much better, much much faster and much much more stable (in the right hands of course, the dfi is designed to be used by more experienced people in my opinion), I have winchester 3000+ and san diego 3700+ as well, the asus had numerous stability problems and asus also produced i bios one day that ruined the hardware monitoring chip on the board and even when flashing back to differentr bios, was far less stable, so we are talking shoddy board and shoddy bios updates for the asus, so who please explain to me again which is more stable the asus or the dfi board.
Also please try and post in the correct topic, this post is dedicated to dfi boards not Asus, aslo try to use that thing between your ears and not antagonise people and think before you post as you are more than likely to get flamed or put down severly by far more experienced people, just cause you have made many posts doesn't mean you actually know anything other than how to press the reply button!
