I have a 6850 at 260KH/s OCed, with two other cards in the tower (Antec 1200 V3). 6850s are a good buy used. (For reference, that is at 915 core, 1000 mem, and 19 intensity. I could probably downclock the memory at least 100, however, I don't pay for the electric, and the heat is welcome right now, so I'm not going to.)
Anyways, the offer fell through, BTC is going for 60% of what it was when I originally made the offer, so....
Thanks for the words of support.
You're welcome, it's the least I can do. Also, just on a whim, I downclocked the 6850 memory to 850MHz(3400MHz effective) and it didn't hurt my scrypt speeds with the core at 915MHz.
Barts works in mysterious ways.
Barts just has a lot of memory bandwidth for the amount of processing power it has.
