Oh well at least the motherboards for the 939skt CPUs are not expensive like the CPUs still are.
You might want to go for a ASUS A8N SLi-Deluxe or something of that level.
Since you are not going to be installing XP on the system one of those motherboards are fine.
Certain ASUS A8Ns like the A8N32 and Sli deluxe do not like XP SP3.
Don't understand how the chips have held their value.
