It is a very nice link, thank you so much.

The guide can of cause be used to control the 2 cards, but it also explain how to crossfire the two cards.
I was kinda assuming that crossfire could not give you any extra hashing power in scrypt minings, since you are already running the GPU's at maximum efficiency, is that assumption correct?

I have a scrypt rig where I recently added one extra HD 7850 (so I have 2 in the rig now).

OS: Win7
Miner sw: cgminer

I have been using am using AMD Catalyst Control center to control memory/GPU/fan speed.
However with the extra card added I can only control GPU1 with Catalyst Control center, GPU0 runs with standard settings.
I have a good cooling system so there is headrung for getting 10-20% extra hashing by optimizing.

Any ideas/suggestions how to optimize both GPU's - is there some other SW to control the GPU's?
