We had already established that the GA chip is 20 times less energy
efficient. So one GA chip at 5 Watts agrees with 250 mW of the heavy
stuff. That is a 10^-3 part of a $3000 investment.
So the GA144 should go at $3 a piece including the PCB, to be
competitive.
[All based on an overly optimistic view of the GA144 capabilities.]

So neither the bit-coins/Kwh nor the investment/Ghash favour the
GA144.

With a second major attack on Bitcoin by law enforcement,
it would seem the "Bitcoin war" has started in the U.S.:

"Bitcoin exchange [BitInstant] CEO arrested for money laundering"
via CNNMoney.  Shortened link is through bit.ly:

P.S.  No, I don't own or possess or control or use any.
So, please don't shoot the messenger.
