Just got my 3rd monitor for Eyefinity, but there's a big problem

I can't find any current guides for setting up eyefinity and I'm too stupid too figure it out on my own. But I think I know the problem I'm having. I can't hook up all 3 monitors to my graphics card. 2 are plugged into my integrated graphics and the primary one is plugged into my 7950. I don't really know how to go about troubleshooting this other that asking the anandtech forums.

Here's is a picture of my CCC. As you can see, it detects all 3 monitors, but will only let me select my primary one.

They all need to be plugged into the 7950. Why can't you do that? What model card and what are the connections your monitors have?
 
As far as I know all 7950 come with at least three video output options. Your computer is trying to make you choose where you want your video to be processed and sent out (integrated or discrete chip). Can't choose both. As 3DVagabond asked, what's stopping you from using your 7950?
 
The easy fix would be to connect all video cables to the 7950. Don't connect the video cables to the other video card.
 
I can't plug my monitors into my gpu because they're older 1680x1050 monitors and they only have vga and dvi while the 7950 only has a single DVI. I guess I could get some adapters though.

That's what you need. Make sure that at least one of the monitors is connected to a DP connection. Although, if you only have one DVI, you'll have to do that anyway.

Too bad you didn't check with us before buying your card. We could have let you know what you needed. Sometimes it's worth paying ~$10 more for a card that comes with the adapters.
 
HDMI->DVI and DisplayPort->DVI is easy - you'll only need single-link adapters because your panels are <1080 resolution.

Order them from Amazon or Monoprice - we're talking about ~$10 here. No biggie.
 
You'll need one Active displayport adapter, around $30 for the single-link version.

The HDMI-to-DVI adapter can be passive/cheap.

You may see dual-link active display port adapters for around $100, but won't need that unless you have a monitor that is 1440p or 1600p (e.g., bigger than 1920x1200 or so). I use my passive displayport adapter on my 1920x1200 no problems.
