Just finally ordered another Asus 5870 to keep my other one company. I have it plugged into one of the new 27" Dell screens and was finding a couple of my games were sluggish at full resolution on the screen and wanted to sort it!

So, questions.

1) Do I need 1 or 2 Crossfire connectors to link the 2 cards together as I can't find the one that came with card 1 (Doh!)?
2) One assumes I simply choose 1 card as master and this is the one I plug into my monitor?
3) Anything else I need to know about I've missed?

Card should arrive tomorrow so will plug it in and give it a go but would welcome any pointers that might be of use (correct drivers etc)

Cheers

You don't actually need a bridge at all, but one is fine. :)

You just turn off the PC, connect the second card, turn it back on, check crossfire is detected (I use GPU-Z) and away you go! If it isn't enable you might have to force it in Catalyst Control Centre.
 
1 - 1 will be fine
2 - Pretty much (try the "top" of the 4 DVI-D Connectors)
3 - Hopefully not - You "may" have to adjust your PCIE Frequency (101 usually works)

Let us know how you get on :D

EDIT Josh P - I can't get CCC to recognise the second card without the bridge in place and tested with and without and definately isnt being used

CCC doesn let me "tick" enable CF and GPUz reports as CF disabled :|
 
Dont listen to a word anyone says if they tell you to use 2 bridges mate:D In fact if it is a ref cooler the second bridge will effect the exhaust port on the card.

10.4 drivers on the amd site work well for me
