2 year profit (after electric and the set up costs are covered)
BFL expected at .20 KWh $91,620
7990s expected at .122 KWh $76,765
Wouldn't the 7990's use more electricity than the BFL's?
Instead of trolling, I shall point out that there is a hell of a lot more to it than that, such as warranty, resale value, etc. Try re-reading the first post in its entirety.
Thanks, I kinda got caught up and stopped reading after I hit that point
I also thought you were referring to the electricity usage for some reason, not the BTC-KWh. Man, I've been terrible at noticing the obvious lately! I haven't even started drinking tonight!
