Look impressive !
What nps does zappa get usually ? (I am assuming only nps changed w.r.t normal
version here)
I usually remember seeing 200 - 300 knps at icc , cant recollect acurately and
maybe it is different for this position too ..

Let me redouble my efforts in bullying someone into giving one opteron beauty
for cct6 to me :) - preferably a dual or a quad opteron ;-)

By the way , assuming you bought it , how expensive was it ?

All the best for cct6 !
