Im planning to purchase 2 more monitors to my ve24inch asus led monitor.

I have 3 questions

My fps in crysis is 72fps average max. In eyefinity 3 monitors would that drop to a third? like 72/3=24fps

Where would i connect the 2 other monitors? My second card? or the 1st one.

Finally for those who have it? Is it worth it?

I have two 5850s and the performance lose isn't just divided by 3. I can't tell you exact fps but it depends on speed of your GPUs some take more of a hit than others depending on amouts of ram and clock speeds and memory bandwidth. Also at least on my 5850s all monitors get plugged into first card. I have 2 DVI, 1 HDMI, and 1 display port. You can can a combination of any two DVI, HDMI ports but the 3rd monitor has to be display port. AKA you cant have 2 DVI and 1 HDMI.

Thanks a lot for the input. Im looking for benchmarks with eyefinity too see the impact so far and it looks my fps will drop by half. Hopefully 2 cards is enough to max BF3 on eyefinity setup at 5760x1080

I just upgraded to 5760x1080 eyefinity last week with my two 6970s. I only got to play around with it for a day before I had to leave on vacation, but most games still played at 60+ FPS. Crysis Warhead went from 60 constant maxed out to 35 FPS average maxed out (although I was surprised since it felt a lot lower than 30 FPS to me, but maybe that's because I'm used to playing at an average of 60 FPS). So the FPS hit isn't as bad as you would expect with such a high resolution. As for connecting the monitors, they all go to the first card. Two of the monitors can be connected with whatever interface you wish. Any subsequent monitors though have to be connected to the (mini) displayports on your card. If your monitor doesn't support (mini) displayport then you'll need to buy an ACTIVE adapter (that "active" bit is extremely important since a normal adapter won't work for eyefinity). If your monitor does support displayport inputs but your card only has mini displayport inputs, you'll still need an adapter (although with the MDP to DP adapter it can be passive or active). Don't use the MDP to DP cables though as all of them are apparently manufactured incorrectly and can cause a lot of havoc on your PC. And yeah, it's worth it. It makes things much more immersive when you can turn your head or eyes in real life to look around in the game. The extreme field of view also gives you an edge in multiplayer games, and it's amazingly helpful for flight sims and racing games since it makes the internal camera views actually viable. Even if you don't game much the increase in productivity you get going from one to three monitors in terms of multitasking is stunning.
