I have a GTX 960 2GB, and wouldn't mind some cash. I know mining bitcoin with it would maybe produce a few pennies a year, but someone told me there are other mining networks that aren't as inflated as Bitcoin. Also, I'm thinking about upgrading to a 1060 soon (for gaming) and use that for mining overnight/during school, if viable. Thanks.

Please note that much of the mining software for a lot of these coins contain malware, so be very, very careful before installing such things.
