Take em back while you can unless you want them for gaming. Mining isn't going to be able to pay back the cost of the cards any time soon, and it's getting worse.
Just my .02 BTC
Thanks for the advice friend, I'll probably take them back later today. I can't deny the fact that it was a fun experience though. I'm gonna store my wallet.dat on a USB drive and put it in my closet. Hopefully when I pull them out 3 years from now, it'll still worth something.
