I like DFI because of the overclocking options (virtually endless). You need to have a good PSU, RAM, and visit DFI Street. All well worth it. I'm running stable fot five months at a 28% overclock. Not a recordbreaker, but pretty good for a nubber.
I highly recommend the MSI K8N Neo4-f motherboard for s939. My friend who was a noob built his and had that mobo and he set it up pretty easily. It's not a bad OCer as well, it's a very solid mobo and it only costs around 80 bucks on Newegg.
