hi guys just want to ask what's the maximum hashing speed of this card? and can you give me a configuration/oc/ for 6 cards and mining os settings.... also what is much better 2 sets of 3 cards or 1 set of 6cards xfire off. thanks

I don't know your specific model but the general attainable speed for 5870s is in the 400-450MH/s range depending on OC.

Concerning the 2x3 vs 1x6 rigs it depends on what your are trying to achieve. If you are trying to overclock the cards you should go with the 2x3 option simply because a 5870 can easily pull over 200W when you start increasing the voltage while overclocking. 1x6 is much more preferable if you are after efficiency on the other hand.
