Need to provide a little more info....
you want DDR 333 or 400 support?
Are you confident that you don't want any of the following:
Lan?
RAID?
Intergrated sound, video?
Additionally:
Overclocking options?
USB 2.0?
Firewire?
AGP 8x or 4(2)x?
FWIW, if you are not going to overclock, I had been inclined to purchase an Intel 845G or 845E (your basic vanilla board). However, I will be pulling the trigger on an ASUS p4s8x myself early next month. I don't overclock, but I believe with the DDR 333 support and 8x AGP I will be good to go for 3 years (hopefully)
