Does Cross Fire help?

[Fuzzy]

If you have 4 Radeon 6950s in a machine, will connecting them all with crossfire bridges increase you Mhash rate?

No, working is distributed individually to each GPU if anything it might slow it down by something probably unnoticeable because of the extra cycles that enable CrossFire.

[SomeoneWeird]

No. If anything it will decrease it.

I would say no, crossfire works by alloting half the screen for one card to render while another one renders the other half. In mining the Gpu is being used for math calculations so crossfire would only make things worse i would assume.
