ATI 4890 CF - CF Bridge Question

post #1 of 5
Thread Starter 
I was under the impression that I would only need 1 CF bridge for my 4890s to operate in CF. However, in a lot of builds, I see people running two.

Do I need to buy another bridge? Will it make a difference?

Thanks.

You only need 1. Adding another can reduce fps in certain scenarios.
Testing has shown a 1fps increase in an old benchmark when using 2 bridges. Other than that, it will have 2 effects.

1. No difference at all.
2. Minor potential of negative performance. (again, in certain scenarios.)

Short answer, just use 1. It is all you need. People run 2 because they like the look of 2.

I always assume that if its something I've never done before on a build and the gains are minimal at best and its cost would be more then I won't do it to start off with it.

Enjoy your build!
