Just one more thing. Red Furys are really cheap and overclock quite nice to stable 3ghs. I run 14 red furies (2.9 - 3.1 ghs) and bought them for about 80 euro a piece. Current prices for red furies are 65 euro in a shop in Germany.

Will you make money on them? Probably not. But if you like to get into mining buy a stick or two and keep the network going.
