At $79 all you are missing is a couple of minor features of the NForce 250 chipset. You still get the two big features: Full HT performance and AGP/PCI locks.
I think I am personally going to take the plunge into Athlon64 with this board. At $79 I can get it, build my system and then if a really kick butt board by Abit or Asus comes out in the next few months I can pick that up. Also, the Via K8T800 Pro (working AGP/PCI locks and better performance) is supposed to be out in the near future. I think I am going to get this puppy so I can have Athlon64 goodness now and then just treat it as disposable...
