I have been using ethminer for AMD 6800-6900 cards about 3 weeks.
I use it because it is free and as far as I understand it performs well.
However, I am still not sure, I might be missing something.
I could not find as many resources as other miners.
what is your opinion?
Can you tell if you have experience?
I guess nfsminer replaces ethminer.
But the question linked here remained unanswered, it got me thinking.....?
