There really aren't any boards out today using the Ultra 400gb chipset, and don't expect many in the near future. While the chipset is somewhat promising, it has been discourage by many for the fact that it DOES NOT INCLUDE SOUNDSTORM. I myself do not use SS anymore, but for many others this is seen as a necessity.
Furthermore, you will also not see many motherboards with this chipset for the sole fact that most vendors are moving towards providing solutions for the AMD64, which has proven to be a better seller than what most people thought. Therefore, most resources will go toward motherboards based on either the NF3 250gb, K8T800 Pro, or Intel 925/915x chipsets.
Lastly, when it comes to socket A systems, the NForce2 chipset is king. While this is not necessarily the case with an A64 platform, the Nforce2 provides greater overclockability and top-notch performance even to a VIA K7 solution with a working AGP/PCI lock.
If your friend does in fact want to build an Nforce 2 system, he should look to none other than the two current champs of its kind: the Abit NF7-S or the DFI Lanparty NF II Ultra B/ Ultra Infinity series. I myself have the DFI and experience no cold boots and I have noticed an increase in my 3d performance clock for clock over my old Abit; however, this is not to say that the Abit is without its merits as it carries a very close following of enthusiasts and bios modders and over it's year and a half lifespan has become probably the most stable motherboard available for an Athlon XP. Your best bet is to do a little forum jumping and soul searching to determine which solution would be best for him. My suggestion would be for the DFI of course but these boards are meant strictly for the enthusiast and as such are not catered toward the average user or those who are not willing to compliment a top-notch motherboard which top-notch parts (i.e. Bh-5/bh-6/OCZ EB and Mobile Bartons). In the end, the choice is yours, but good luck either way you go...
