11 Mh/s QUARK, RELEASE 65---
With a little tuning, and using the "cpu-mining", "-C" switch, I was able to get these results with my Win 7 x64 work computer and an EVGA GTX 960 SSC graphics card:

The card is mining with SP-mod release 65, and a +80 core/+240 mem overclock. There may be room for better and faster tuning, but this appears to be a stable setting for my machine and card. Higher overclocks bring as much as 11.2Mh/s results, but have been less stable.
Earlier this week, this card was mining Quark at 10.6Mh/s. With the cpu-mining switch, "-C", performance has improved. My other rigs on Linux have shown similar gains. My 6x EVGA 750ti FTW rig mines at 40Mh/s, up from 38.5Mh/s, and the cards run from 6.6Mh/s to 6.8Mh/s each. My EVGA GTX 970 FTW+ cards now mine Quark at 16.5Mh/s each, up from 14-15Mh/s each.
I hope the other bugs are worked out, I'd like to try solo-mining VertCoin. I also noticed the lower poolside VTC hash-rate reports within the last 2 releases, hope it is fixed. --scryptr
EDIT: Better results are obtained when using an intensity slightly less than the maximum acceptable/stable. My launch string: ./ccminer -a quark -i 23.9 -C --cpu-priority 5 -o stratum+tcp://quark.pool.com:port -u a -p x

My clocks are currently +90core/+270mem. My results are +160kh/s from the first (top) posted pic. Adjust per your hardware. --scryptr
