joolzg: I live in .se too. With my 7970 I make at least twice as much as electricity costs. That's not unimportant but my driving force is the anarchist part of it, and a currency that will work even when the world economies go down the drain (yeah I'm a pessimist). Call it an investment or insurance.

I must admit the heat is becoming a serious issue tho. Not to mention the noise. But as long as I get more back than I put in I'll keep going.
