I strongly suggest you look else where for an asic solution if the earliest is august delivery. I'm still happily mining away with my 7970, and at current prices it's producing $5 profit a day on top of all the coin it has produced since August 2012. It's been a great investment so far and plays all the latest games to. Good luck again.
At $265 per Bitcoin your only making $5 per day? I think your calculations are a bit off.
Why don't you look at the day of my post, and the value around that time, genius.
