Motherboard Experiences?

   My Athlon XP motherboard and/or CPU are acting flakey, so I'm
using that as an excuse to move up to an Athlon 64. What are people's
experiences with the various chipsets and motherboards that are
available? I don't need a huge number of features; I'll probably
reuse my existing RAM, drives, and video card. Any positive or
negative comments would be appreciated.
   Thanks.
