Well depends on your needs, budget, etc...
The nForce 2 boards are starting to look good, BUT they are new and they still may have some bugs.
If you are buying in the next 2-3 weeks I would look at the Epox EP-8K9A2+. It is a Kt400 board with ethernet, 6ch Sound, Raid, serial ata, usb2.0, and should overclock like a champ.
I think it gos for $125, which is cheap for all that it has.
