Hi!
I have a 6950, and im thinking...should i buy another 6950 to crossfire with, or should i spend those 230€ in bitcoins instead?
With difficulty rises, im thinking its better to buy bitcoins. If i buy them now for around 8$, i'll get around 33BTC.
If i buy a 6950 and mine (~760Mashs/s), with current difficulties, i'll probably make 40btc in a couple of weeks, but its getting harder and harder, and with another 6950 the electricity bills will rise a lot!

INVEST !

Mining will soon become unprofitable because of extreme difficulties. I expect about 300 000 difficulty next. Just look how deepbit.net hashing speed rate increases every minute now and deepbit is about 50% of the whole network.
