Any nForce2 mobo with SPP + MCP-T (or MCP2 if you don't want SoundStrom, SATA (RAID), FireWire, and Dual LAN). I thought when KT400A is available I would recommend that but KT400A is once again beaten by nForce2. So stay away from VIA until they finally comes with senses. For nForce2, MSI K7N2 series or Asus A7N8X series are very good, Epox 8RDA+ is another good choice for overclocker, and I'm hearing some good words on Soltek recently also.
You never know how stupid you are until you have done something stupid enough for you to realize it.
