Yeah!  that's the right word.  Thanks for the correction, I've been using it
wrong for a long time. :(

I do like the cpudyn, I have it running on my Athlon64: 1000MHz unless
I'm using the machine or doing something in the background. :)

I just wonder how a single Opteron compares to an Athlon64 of the same
frequency when running X, myth, transcode jobs, etc.  According to MSI's
website my motherboard can take either of the 939-pin breeds.  When
I upgrade my processor, I'd like to get the one more suited to the job I
need.  Basically, I wish I knew which one would be better for our
application.  I have yet to hear someone point to one processor as the one
for a myth machine.
