1. Socket 939(can be upgraded to accept dual core X2 processor)
2. Has way better video
3. Better chipset with better driver support
4. SATA will support SATA hard drives
5. GB LAN
6. Supports 4GB of memory
7. Firewire
8. ASUS great quality, support and updates.
all of that and its only $21 more...
But it will soon (very soon) make buying 939 socket CPUs more difficult.
