Doesn't it need only 1?. I use 2 for my SLI just because it looks better.

Hmm...there is only one slot available on the 3870X2...therefore one bridge can only be used...for the 3870 there is a reason for have two bridge connectors; drivers can support up to 4 gpu in x-fire...thus you could if you have the space on your mb & case(open pc if no case room)...the option of adding upto 4 cards...or three cards such as 2-3870 and one 3870X2 for a total of 4-gpus...

one connectors is all that is needed for bridging two cards...while the second connector would be necessary for bridging to the 3 or even fourth card if you had let's say 4 separate 3870 cards....

There's your answer~!!!

For crossfire x or native,two bridges.
post #10 of 15
Only one bridge is needed when running two cards as thunder_2008 stated. Also there has actually been a benchmark run (cannot remember the site currently, but google is your friend) that tried to test if there was a difference between the two and when two bridges were used the results were slightly lower than if just one bridge was used. If I happen to find the site that did this I will post it.
