I've just acquired an Asus crosshair II 790FX for $50, pretty happy with the buy. Granted, it didn't include the SupremeFX II Audio Card it's suppose to come with and I couldn't find the port for the front panel audio so I assume it doesn't have one but it supports some early AMD Phenom II processors and three way SLI. Pretty impressive for a board that was released about three and a half years ago. I bet it'd still make a pretty decent gaming build.
