Bitaxe Gamma vs NerdQAxe++

The NerdQAxe++ hashes about 4 times faster than the Bitaxe Gamma, so its chance of finding a block is about that many times higher. It also draws about 4.2 times the power (76 W against 18 W). Per terahash, the Bitaxe Gamma is the most efficient at 15 J/TH. The Bitaxe Gamma is the cheapest to buy, from about $110.
