Bitcoins ! ?

[Mark]

How does one go about this mining? And how does it work, what does one mine? So with your 4.77 million hashes a second, how long does it take before you make that 1 coin, or 20 bucks.

Going off this chart: https://en.bitcoin.it/wiki/Mining_hardware_comparison - I could get around 35million a second off one machine.
