I'd be very interested to see any application benchmarks you've run.  In 
my testing <http://www.duke.edu/~jlb17/optxeon.pdf>, Xeon 5140s blow the 
doors off Opteron 270s -- moreso than the clockspeed difference would 
indicate -- in almost all my benchmarks.  I was leaning the Xeon way for 
any new purchases, but I haven't had a chance to test the new Opterons
