Whats the best way to hook up dual monitors with crossfired cards

[stitous]

I have a crossfired pair of 4890's and I also run dual monitors I was wondering if it mattered whuch of the four ports on the cards I used and for which to use on the main monitor?

I'd use the top card for both monitors.

tbh thats the only way I can get the second one to work at all. But what if I had four how do you get the second card to send the signal

AFAIK one can't use more than 2 monitors for gaming on the HD4K and below, and one can use 3 on the HD5K. One can use 6 on the special eyefinity series.

When you have crossfire enabled you can only use the outputs on the card that is considered primary. If you disable crossfire you can then use the outputs on both cards. When I had my 4850's in crossfire I had profiles setup for crossfire vs. Non. Without crossfire enabled I had 3 monitors running but when gaming and I needed the extra power I'd activate my profile with crossfire and go down to just 1 monitor.

Like sitous said, the newer ATI cards can run 3 monitors per card rather then 2. Currently I'm running a 5850 with 3 monitors. Eyefinity is lovely...

thanks guys this was very helpful also which is the primary slot the one closest to the mobo or the outer one or does it not matter in the slightest?

Hi AdioKIP - and others here ... I need help please..

I have 3 monitors - 26" ASUS <1920x1200> & two AOC 17" <1280x1024>.
I want to buy a new computer (i5?).
I use computer mainly for office applications + photos & video from camera.
I want 3 screens to run independantly (not one big screen).
I may start to use some "point & shoot" games in future.

What video card / cards setup should I start looking at?

Is Eyefinity not possible when needing 3 independant screen (not one big one)?
Is Crossfire the way to go?
What i5 & MB combination is the best price point?

Thanks in advance....
Martin..
