One of the guys I worked with actually dropped over 2 grand in parts for bitcoining. ASRock Extreme 7 board and 4, 7970 cards. Over 2 Gigahashes. He's calculated that it'll take only 6-7ish months to pay off his computer at that rate, and from there it's pure profit. He pays flat rate for electricity where he lives, so he's good to go.

Basically after learning this, I started running a client on my little 6870 card, and am now in the market for a 6990 that will serve for a little extra cash when I go off to college. Can't go wrong with Dual GPU =)

Thanks for the link, I'll definitely use this in the future.

The current requirements to get out of the newbie section aren't all that hard. I joined 7 minutes ago and have 3 posts already. Wow, so difficult I don't think it's worth it...

You better have a pretty strong background in coding, as well as IT and web security.

Even so, open source? WAT? 

The Radeon HD 3000 series don't support openCL, you can't bitcoin mine with it. Besides, even if you could you'd make next to nothing.
