In my experience athlons are fine.

Dual athlon (appro/small outfit):
sine:~> uptime
  9:16pm  up 44 days, 11:42, 20 users,  load average: 2.00, 2.31, 2.60

Dual athlon (lnxi/small outfit):
beowulf:~> uptime

Homebuilt desktop (single cpu):

Of course there are bad motherboards out there, and of course people
often ignore a vendors recommendation on dimms and instead of getting
certified memory they get generic memory from a random vendor, or a
non-athlon certified power supply etc.

Buy quality stuff the chances are better that it will work (amd or intel),
buy crap and your likely to have more problems.  

The last big vendor athlon I bought was a micron, worked fine, had a
ibm deskstar death, but otherwise worked.  Unfortunately it was sold into
microsoft slavery so I can't run an uptime on it to see how long it's
been up 8-(.
