Looks good.. Should do rather well.. I'm not a big fan of MSI, but I haven't heard anything bad about their newer P4 boards..
I don't know off the top of my head if that board will Dual Channel the DDR, however, with the value select ram, I would be carefull about that.. Without having matched sticks, you may be playing with the CAS and voltages to get them to sync properly.
Have a good one,
