# of crossfire bridges

So I far I googled and checked ATI forums there is no conclusive answer.

I'm crossfiring two 5750 cards together, but there are photos of setups with one and two bridges. The diagram on ATI's website has two bridges, but many photos I dug up on tom's hardware and guru 3d has only one bridge. So am I fine with using one or should I put on the second one.

well ive dug up on some tec post (not in english so i wont link them) but from my understanding you get better results with both of them, the best way to find out is to benchmark with one and then with two. ppl are saying that they had up too 200 points gap in favor for the two set up.

cheers.

There seems to be a very small increase in performance when using 2. If you have 2, using them can't hurt, but if you only have one, don't go out of your way to get another.

It works either way, but 2 is "better"... at the least a second one gives you a spare to test out in other rigs as needed.
