Title: Bitcoin Mining GPU Comparison spreadsheet Post by: rckid1 on February 05, 2012, 04:11:21 AM I am looking into upgrading my Multi Use comp (Gaming/Mining) and decided to do a hardware analysis based on initial cost and theoretical gain/cost to operate to get the number of days to break even. I could use some suggestions as I am sure some of my data is skewed as far as power usage values go, but I am pretty confident in my MHash and card pricing. I also included an efficiency hit for multi card setups as I figure the additional heat would lead to additional power draw and down time. Anyway feel free to flame or criticize away that is why I am posting this, also if anyone would like to see more cards added I would be happy to add them.

You cannot ignore this. you should consider these values with a potential increase of difficulty or decrease of price of the bitcoin and see what it does...
