More to the point, given the market that Orion is selling into (offices), 
what's the power consumption and noise level of the quad opteron?  If Orion 
has 96 processors and you use your 4 Opteron/12 Efficeon ratio, that's like 
32 opterons (i.e. 8 quads).  If opterons are 100W each, that's 3200W, which 
is quite a bit more than the 1500-1800W the Orion box is shooting for.
