Are you going to get the $4680 unit that can only crunch 600GH/S when the difficulties went up yesterday?
At least it's a good news that the product they made stand up to the spec stated in March of 2013! How many BTC are you making a day from this unit?
I won't purchase the 600GH/s card from them. I'll wait and see if they can hit their future targets before I jump on that train again.
BTC's a day with 30GH/s is around 0.02 btc. Or approximately $7.00 per day. Of course that will change at the next rise in difficulty.
