Thanks for this! I read through all the comments and I'm just going to see how it works for me for several days before I try something else like NiceHash. Here's some info that someone may find useful: My PC is running Windows 7 Home Premium 64 bit SP1, AMD FX-8320 8-Core processor, 16 GB RAM, Nvidia 4gig Geforce GTX 760. When I am mining, the pc is using 125 more Watts according to my power supply. The GPU temp hovers around 60C, CPU temp is about 28C. Running a benchmark crashes the program, so I stopped trying to benchmark. Using "Smart Miner", it mines XDN and FCN, but I put some CPU cores on ETC and actually got a tiny deposit after less than 6 hours or so of mining ETC : 0.000009583208. Then I switched my GPU to ETC and left 4 CPU core each on XMR and FCN. Getting 5.15 MH/s GPU on ETC, about 85 H/s on 4 CPU cores each on XMR & FCN. It won't let me mine ETC and ETH at the same time. This might be interesting to someone that has more experience in mining.
