There are a lot cryptonight miners around that a much better than Claymore's. So if he doesn't want to continue development - leave 0% fee and exit is a right move!
Name it.
xmr stak
cast xmr
sgminer-gm 5-5-5
SRBminer
Thanks for those recommendations. I'll give Cast and SgMiner a go to see how they do. I have a feeling Cast may suit me well.
I use xmr-stak or sgminer. Some motherboards (or is it the cards?) seem to like one over the other.
Some seem to prefer CastXMR but as it is closed source, I can't verify that the reported hashrate isn't a lie, so I don't use it.
