I am getting the DFI Lanparty Ultra-D mobo. dfi has an awesome forum with so much help available if you need any. I will also be OCing and alot of people have recomended the DFI boards.
What Kraut suggested is good, but the MSI K8N Neo4-F will definately be okay too. It just doesn't offer as many features as most the dfi boards do.
I have the msi k8n and I love it.
