Crossfire, 2 bridges or 1?

[spathotan]

I couldnt find anything about this in the SLi/Crossfire FAQ, but does a 2 card Crossfire setup with say, the 4850, need 1 Crossfire bridge or 2? And if it only needs 1 is it dangerous to use 2, just out of curiosity.

I can't remember off hand where I read the review, but they testetd one and two crossfire bridges and there was NO difference. The reason there are two attachment points on crossfire cards is so you can crossfire three or more cards. For example card One to card Two, card Two to card Three, card Three to card Four.

For 2 cards, putting one or 2 bridge makes no difference.

Ok, thanks guys. Ill use 2 bridges for the nifty factor

i tested it out and the other post was right.you only need one bridge for two cards.my 3dmark06 score with one was 18128 and with two it was 18058.dont know why it dropped probably just slight changes with system performance.12500 one 3870,18100 in crossfire.

That is within normal variation. I bet if you ran it twice without changing anything, you could see that much difference easily.
