3xMonitor 2xGraphics Card Issue

post #1 of 4
Thread Starter 
I currently have an issue I can't seem to resolve. I have a 4890 1GB card and a 4850 512MB card powering three monitors. I have a Display Port coming out of the 4890 to a single monitor and the 4850 has a DVI and HDMI powering two other monitors.

I've been playing world of warcraft recently and noticed a problem. All of my graphics processing is being done on the 4850 (90-95% activity) and nothing is happening to the 4890 (0% activity), even when World of Warcraft is on the monitor that is connected to the 4890. I checked CCC and its showing the 4850 as the "Primary Graphics Adapter", however the 4890 is in PCIe01 and the 4850 is in PCIe02.

My questions here are:

1) Is it normal for only one graphics card to be handling the load for all three of the monitors, even if its not connected to them? My central monitor is only connected to the 4890, which has WoW running on it. If so, how do i select the 4890 as the "Primary graphics adapter"?

2) Why is the system choosing the 4850 over the more capable 4890 to do the graphics processing?

I was always under the impression that it was simply the graphics card that the monitor was plugged into would be the one handling the processing for that display.

do you have the cards in xfire? i would try switching the pci-e slots and connecting two monitors to the 4890 and one to the 4850

edit: it would be helpful if you entered your system information in the user cp so we can see your hardware config

I added a few of the pertinent system information bits to my system build. I am NOT running crossfire, which is why I'm wondering why only one of the graphics cards is handling the whole load.

Should I have these cards Crossfire bridged, but not actually have crossfire enabled? I'm trying to seperate the workload across the monitors like this:

3 Monitors:

1 main one in the center for gaming, run only by the 4890. The two monitors on the side are plugged into the 4850, which will not be used for gaming, simply for chat/web browsing/etc. I want the crappier card (4850) to handle the load of the "non-gaming" tasks, but the 4890 to be dedicated to the central task (gaming, movie watching, etc).

Thanks for any help in advance.
