You guys are missing the point! Unless you like can't get anything else at all this is WAY too expensive to mine btc at that speed. You can buy 60Gh units for under $1000 from BFL now. Also there will be a BIG drop in price because 20nm chips are coming out in like 1 month. 2TH/s miners are already being shipped to lucky few. Anyways, I'll personally wait, mine some scrypt until I can get some decent btc miner.
