Well done. Didn't really expect any takers anyway given my lack of rep. But, honest question, why do people give out info like this? Given that we're all competing to discover the next correct number, why give away one of the inputs?
Really it's irrelevant. People so interested in mining would have simply saved more towards a 6870 or 6950 which offers similar or better performance, and has a higher resale rate. People won't stop upgrading just because one model isn't in stock; they'd move on to the next best performer in terms of hashrate/$.
