Just spotted this bit of info at NvNews.net:

Take this with a pinch of salt but a website has what it claims to be an AMD Athlon64 3400+ and AMD Athlon64 motherboard. Basically it's nudies of an ASUS board with supposedly VIA's KT800 chipset and the Athlon64 3400+. It also has some nudies of benchmark results that they claim is from the said components. What is intersting is that (if its true) the default voltage of the Athlon64 is 1.5v. Pretty low eh?

Athlon 64 First Look?
