Just wanted to let you know that because of Ethereum, a cryptocurreny you mine similar to bitcoin, Radeon cards, even some older ones, have become very popular for mining. They are better at hashing and have lower power consumption than Nvidia cards. They're selling out and its driving the price up past original by a good margin. So, my advice is.... sell your radeon card and upgrade to an newer Nvidia with your gain. You can find what you're card is worth here.
