Bitaxe Gamma vs Bitaxe Supra

The Bitaxe Gamma hashes about 2 times faster than the Bitaxe Supra, so its chance of finding a block is about that many times higher. It also draws about 1.3 times the power (18 W against 14 W). Per terahash, the Bitaxe Gamma is the most efficient at 15 J/TH. The Bitaxe Supra is the cheapest to buy, from about $60.
