I have a gaming rig with 7 cores and a GTX680 that I'd like to use for mining. I set everything up, and wanted to try solo mining, and I was only getting 2 Mhash/s. Does anyone know why this is? I've read that my card should be getting somewhere around 110 Mhash/s.
Sounds like you're mining on the CPU 
Also, solo mining at 110Mhash/s?
You're going to want about a thousand times that before solo mining is any sort of a good idea
Hell, unless your power's totally free you're still not going to make a penny
