I wouldn't know personally, still waiting to get one, but from what I've seen and heard, the Asus p5w dh needs a bios update or two just to be compatible with conroes, it isn't compatible out of the box.
The selection for the higher-end motherboards for Conroe is :cough: :cough: limited and WAY overpriced. Wait for a month or two for more stable boards and for the prices to fall.
a bunch of motherboards, even like $50 ones will work with conroe, but its the overclockability thats a problem with them. and not ocing a conroe is practically a crime. and the boards that oc well are pretty expensive...
*wishes for something amazing like the dfi lanparty nF4 SLI-DR or Ultra-D*
