Still holding and keeping an eye on Yacoin. =)
What was the fork fixing/ changing?
It was a tweak to adjust the trust for chains of POS blocks to attempt to prevent orphaning of POW blocks.
I setup your minerd but am unsure which to use for amd 960t? Both athlon-fx and nocona work but I get horribly low kh/s.
Which version should I use for the Zosma and what kh/s should I expect?
Also am I just wasting electric cpu mining on this coin now that it is gpu capable?
Whichever version works and gives you the highest hashes per second...
http://yacoinwiki.tk/index.php/Mining_Hardware_Comparison is the comparison page for hardware.
Even a low end GPU's gives better performance per watt than CPUs, but mine with it if ya got it and want to. YAC is highly profitable if you know what hardware excels at it and how to maximize what you've got. I keep no secrets, but I've put a lot of time and effort into my configurations and updates to the software to cope with the high N factor, and I'm going to reap those rewards now.
