Topic: Bitcoin Mining GPU Comparison spreadsheet (Read 9053 times)
It does not take the varying value of bitcoin and difficulty. 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...
That page is where I got most of my information. I just used that info to estimate a theoretical break even point for the cost of the GPU.
You might want to look at https://en.bitcoin.it/wiki/Mining_hardware_comparison as this page contains about the same information...
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.
