I've been a lurker in the forums for a while, but I decided to make an account now; so, hello!
Now the question:
Recently, I have been looking into the different options for mining bitcoins.
I tried running a mining client on my desktop a little while back just to see how it all works, and it's rather intriguing (albeit not very profitable on a single, old GPU).
So my question is, if one wanted to get started mining, what's a good setup? I get "free"* electricity, so assuming I had the money to buy equipment,
what would be the most efficient option per dollar invested (ignoring power costs)?
