Uhh, Zed doesn't think so. Neither does Google Spreadsheets.

His bug is far worse than than the FDIV bug, that one was was pretty obscure. m3sSh3aD's brain bug produces far more and far greater errors and in each and every attempt at math.

He posted earlier his electricity costs £0.16 per KwH. to get to £110/month means £0.15/H. So he would be mining at barely over 1000W
Hes mining mostly on heavily overclocked and overvolted 69x0 cards.
To get 3 BTC per day, you need ~3.5GH. @1000W?

Show me a GPU mining rig that gets anywhere near 3.5MH/W.

I think you could do it with some serious underclocking and undervolting on the right hardware. Maybe....

If I ever get bored I may try to see what is the highest MH/W possible using one of my 3x5970 rigs. I think I could make 3.5MH/W.

Nice challenge. Hope you can find the time one day and show us if it is possible !
