The only one out of those two you can actually use is #1.
I am sure you meant a S939 A64 with #2. There isn't quite as much board selection on S939 at the moment as there is on S754, but Winchesters seem to be stellar overclockers nonetheless when put on good boards like the Epox NF3, and with this socket you'll probably be able to upgrade to PCIe more quickly in the event that it does become necessary before you do a complete overhaul of your system.
