Dual 4890 triple monitor

What kind of FPS are you seeing when you use 1 monitor on each of the 2 video cards and play 1 session of Eve per video card?

What PSU are you using to power that system?

Full system specs would be nice.

Sorry

I'll get the performance of 1 session per monitor when I get home from work.

Enable crossfire, the top card is doing the work load for all 3 clients (I multy box wow and have played EVE my self) and then drag to screen that is connected to the lower card. Also kill any program that is unneeded in back ground that uses the cpu and the page file. The page file is important since that is ware the OS often stores the texture data while maintaining the system ram for program data. What brand and model is your HDD?

I thought that with crossfire, you couldnt have the monitor plugged into the second card, that only 1 of the graphics ports would work. If thats the case, how do I hook up the 3 monitors? I will try it and see.

HD is Western Digital Caviar Black 1 TB SATA II, 32 MB Cache, 7200 RPM, 3.5-Inch Internal Hard Drive WD10000LSRTL

Enabling crossfire will not allow you to use the 3rd display.

I'm not sure you will be able to do what you want as windows is kind of funny with things like this. I'd imagine the primary card is doing all (most of anyway) the work. There is not really anything you can do about it. Are you able to run 3 with the single card with non minimized? Minimization will likely prevent most of it from being rendered.

hmm, ok. I will have to check how it performs after work. Are there any cards out there that support 3 dvi outputs on 1 card? Everything I find seems to only have 2.

The only things that support 3 outputs are (eventaully) GTX260 and above Nvidia cards in SLI (you will at some point be able to use the secondary cards outputs) and teh new 5000 series from ATI.

The 5000 series are the only ones that support 3 (or more) displays on a single GPU but one of them must be Display port. A DP to DVI adaptor is expensive and passive ones (the cheaper) are rather hit and miss. I'm not sure how they respond to secondary card outputs while in crossfire.
