Guys, do you think it's okay to use my somewhat-ancient computer to mine for Bitcoins? It's got hardware that was great a few years ago, and an Nvidia graphics card... Might it work?
I'm not really sure mate, since the information you have provided isn't sufficient, but I suggest you give it a try.

Thanks. I figured I might as well try it. It's not going to make me a Bitcoin millionaire, but I figure an extra bit of computational power won't hurt.
