Server grade cards?
Why do you guys not use server cards like the AMD S10000. And does any one know the hash rate of any?
because you can get more performance for less by using desktop cards.

3k for a single card.
825MHz core clock
2x1792 (3584) stream processors
375W consumption at load

629 for a single card
1000 MHz core clock
2,816 stream processors
~300W at load

So for the price of 2 of those, you could buy 8 290x's and have a grand to spare.
the S10000 is nothing more than two underclocked 7950s on one card with ECC memory.
