Bitcoin mining in crossfire

[rishiswaz]

I have a system with a Radeon HD 7870 dedicated just for bitcoin mining, the motherboard supports 2 way crossfire so I ordered another one, there are 2 full length PCIe 2.0 slots, one is at x16 and the other at x8 speed. I just ordered another 7870 and was wondering if I should set up each card to mine individually with 2 separate workers or have them work together in crossfire. What setup would be best? Sorry I do not know where exactly to put this and this was the closest board I could find

Shame you didn't get cards tailored for mining instead.

What cards would be tailored to Bitmining ?

The ASIC cards I believe.

Radeons are good, but nothing compared to cards dedicated to these kind of things.

AFAIK ASICS are separate machines not cards, Application Specific Integrated Circuit. I could be wrong however. The card was DOA so I had to RMA it. But should I x-fire or have two separate workers back onto the main point.
