Two crossfireX bridges instead of one.

I have noticed that in some 2-way crossfireX builds, that some people use two bridges instead of one. Does this increase the performance because there is more bandwidth? or does this reduce the performance because the card stuggles to decide which bridge to use, therefor it add latency to the data bring sent across? or it doesn't increase performance nor hinders it and people just do it for looks?

Is there any hard evidence that supports any of these above questions? If there isn't any then just type your throughts on what you think it does to the graphics cards below.

I use to do that until people said looks crap with 2 bridges and there is no performance increase or decrease with 2 bridges.

I'm fairly sure that Linus clarified this in a Crossfire SLI NCIX video
