Is it more efficient in terms of money spent per GHash?
nobody who has seen one or knows is saying yet. the architecture says it is more efficient in terms of power consumption, but the price of the hardware per mhash/s isn't known yet.
I ask because I have $176,000 US right now. I have another $50,000 or so coming in within the next month.
oh, ignore what i said then. hell, why buy just one?
Agreed. Especially if you are a geek. If you are a geek then you love the public/private key cryptography aspect of Bitcoin, the decentralization, the blockchain, etc, etc
If you are a geek then this is your hobby. Do as you please.
