Ran this overnight in the deepbit pool.. made 0.49 bitcoins, about $11 worth. Worked out it roughly cost me 400W for 24hrs @ ~25c/KWhr = $2.4 give or take. So profit is just shy of $9 a day.....
AMD/ATI cards apparently mine a lot better than nVidia. Have read around and it seems to fairly easy to turn a profit even taking into account electricity costs etc. Might give it a whirl..
So this is distributed processing similar to say.. stanford folding proteins, but they reimburse you for your processing power/time/power bill with e-currency?
