I'm running the Epox EP-4SDA+ and it is really stable. The board has built-in RAID via a Highpoint chip and delivered was just under $110.00. I think you can pick up the non-RAID board for about $90.00 delivered.
I bought it just to see if the SiS 645 was anything to brag about, and am I impressed! The 1.8A is at 2.12 at default voltage and with the retail HSF. After I install the Alpha 8942, I'll really give that core a workout.
