I know you are refered to as "The God of OC" around here but don't say ASUS is a flop I didn't have them for long but didn't suffer any problems with them.
Hence why I said it isn't neccesarily a "bad" board...however if you are serious about overclocking you will run problems trying to do so on the earlier AMD64 boards and they simply lack the neccesary features needed if you want the absolute best stability and flexibility
Furthermore...the big problem with Asus is still their tech support, plain and simple...it is nowhere near the same level of tech support that DFI supplies as well as the fact that DFI boards are tested and tweaked more extensively by the enthusiast community. Considering Asus and DFI fall into roughly the same price catergory, the DFI is better choice by a long shot. I will give the AN832 an honourable mention however it still has the same tech support issues and it's really really expensive and really hard to find
Hence why I said you have a ways to go
