Have to agree with kemosabe79 here. Go for the ABIT. If you are planning to overclock the best way (the only proper way IMHO) to do it is in the bios through softmenu and not through some windows utility.
A little harder but you wont regret it in the long run.
I've been using Abit for the past 7 years, I've never had a bad one yet. Everytime we go with the over-clocking it's always been better to use what comes with the board. I'm not saying that there aren't good programs out there, but what comes with the boards has already been tested and certified.
My company runs the Abit series Mobos, as well as Asus, and 1 is running on the DFI. Currently I am still on the older KW7, but have ordered the KN8 SLI, mainly because I have an Opteron 180 I'm going to run in it, with 4GB PC3200.
We just partnered with NVidia, so I have to go SLI, although up to now I have always used the ATI X-series. From all the research I've been doing and with all that Abit has told me, it's the board to go for stability, until it's time for the AM2 boardset. But that will come when I get another CPU from AMD to test.
