5%?  Winamp/XMMS have never used more than 2% avg for any vorbis or mp3 
stream I've thrown at them so far; this on a K6-III/450 with a plain ol' 
SBLive!.  Or is 5% the CPU load for the entire system with all the 
processes and junk running?

But isn't relating the load on a 1.2 GHz machine rather irrelevant to 
the present discussion anyway?

[For the record:  XMMS takes 0.1% CPU time for 128k mp3, and 1.5% for q3 
vorbis according to top.  This seems odd considering an above statement 
that vorbis is less CPU but more memory intensive.  Is top a bad 
indicator for this?]
