I'm using my Opteron 185 box  ( as well as an Opteron 180) for digital 
mixing and music using Cubase 4 on one and Sonar Producer 7 on the other. 
Both are written for multicore. Both choke when adding and mixing effects
in 
a 10-12 track mix. Badly. I ran Sonar 7 Producer on to the  T7600 Dell 
laptop, installed the same M-Audio MobilePre USB and mixing hardware,  and

believe me, the Intel Core2Duo setup slows down, but never stops and
flakes 
out. Same memory on each. The Opterons are both running RAID0 setups with 
256Kb stripes. The Dell is a 7200RPM laptop HDD. So there's just a bit of 
difference in multicore ability there.
