How much could you potentially make with any of these cards a day if all you plan on doing is mining?
I heard talk when I was in a game where a guy had "very intensive gaming hardware" and he was only making "a dollar a day"
Also, why not just get a miner?
At current difficulty I calculated it comes out to about $450 a month and I don't have any power costs. I have been mining LTC on my "Gaming PC" for the last 2 weeks about 8 hours a day sometimes more and have about 6 LTC. This setup should get me about 4-5 a day. I would like to add that I am by no means doing this to make a profit. I am doing this for fun and to help the coin community. I have been reading this stuff every day and trading what little LTC I have on BTC-E. Trading is a lot of fun too. If I make money then that is an added bonus. When or if I get board I will sell off my hardware and walk away. I think I am more likely to just reinvest into more equipment and re-purpose it if something happens to BTC or LTC. 4 months is my ROI plan though.
