Oh I see. I wish I knew about this "secret" club. I've just started a couple of months ago on my 7970. Only did it a couple of days though. Made $5 worth of Bitcoins over 2 days. Seeing that I was doing 700 Mhps, and others doing 300k Mhps, and I'm only doing .01% of the pool... just didn't seem worth it.
I've started it up again yesterday and the past 24 hours I've earned .02 bitcoins. I'm feeling discouraged yet again by the .01% pool.
It's like the rich guys can get richer faster or something.
Stop asking "why would you do that?" We're in "the pursuit of performance" here.
