Intel has problems too.  This is probably not the best time to be building
a new computer as there are a lot of new (read: immature and buggy)
technologies in play.

If you want something to work out-of-the-box with minimum fuss, go for
Intel workstation/server boards.  They are more expensive, but work 100%
with Linux.  Also, with the latest push for energy efficient servers, you
can get a fairly good performance/watt ratio.

All this from a former AMD champion as well. ;-)
