Hmm,i thought JC showed(near the end of his preview) the completely functional 3 channel Bloomfield system.The numbers from that system were even used by Hornet to make one of his charts for comparison with K10 and C2Q if i'm not mistaken.

What i said in my previous post is only based on logic.No 3 channel/better tuned system can produce 2x the score,it is simply against logic(and what we know from uarch. evolution-Nehalem is the same 4 issue 128bit SSE/fpu capable core).
