? Using 2 Graphics cards

yes, you can add another card to gain more monitor outputs. Id probly get an nvidia card since you already have one, to prevent driver issues mostly.

You can do this just fine as long as you use a similar card. since you have a 200 series card i would recommend using another 200 series card. Unlesss you have windows 7, which will support as many different cards and drivers as you can stuff into it. Windows Vista will not support an ati and nvidia card at all, but you can potentially do it with XP. XP may still have issues so it is highly recommended that you stick to the same maufacturer of GPU and even the same series to lower your risks of driver conflicts.

Is this true? Sweet! I have a few video cards lying around. I'm not sure of the make until I go dig them up. I don't really want to go out and spend more money if I can help it.

I running Win7 Ultimate

Woa there... Do you have an SLI capable motherboard? or are you talking about using plain PCI slots?

If you are just trying to add another monitor you won't need to have an SLI motherboard. Do you have a 2nd PCI-E slot? That would work if you just threw in a lowend card to run a 3rd display. I'd recommend an nvidia card as well, it will have FAR less issues with drivers.

Ok I have a second PCI-E slot and a regular PCI slot. The PSU is only 550W plus I know that I don't have a PCI-E video card. So I was hoping that I could just throw in a PCI video card for the 3rd monitor.

What cards are you using?

Any card old enough to be plain PCI is going to be weeeaak. -But I dont see a reason not to try it.

There's always the option of selling that gtx 260 and getting a 5750! Eyefinity FTW!

That would be a downgrade... The 5770 is similar to the 260 in performance.

I'm saying if all he wants is eyefinity the 5750 is a cheap way to get it. If he wants it then he can get a 5770 or 5870

of course

If you have another pci based video card, go ahead and use it. It will be powered by the pci slot, so your PSU should not be an issue.

In the Bios of your motherboard, there should be an option to designate which video adapter or monitor is to be used for booting and bios messages.

If you want to get a cheap pci-e nvidia card, then I think anything from a 6000 series card on up uses the samd driver.

Is there anything else that I could that extra PCI-E slot for? If nothing important, how much can I get a cheap nvidia 6000 series card for?

A 6200 card sells for <$40. The 210 sells for the same and should be much better.

The extra pci-e slot might be used for a fast raid controller or similar. More likely it would be used for sli. Both uses will be expensive.

$40 bucks and the 210 has an HDMI port? Cool! Maybe I'll go that route. Do you guys think I'll need to upgrade the PSU if I do that?

A 210 should not need a psu upgrade. It is powered by the slot, and is built on a smaller chip technology, so it is more efficient.

I'd throw in a GT 210 or 220. It's probably your best bet.

Maybe another dumb question but by adding 2 different video cards will they work together in processing and rendering graphics? I have heard you can do this, but does it have to be with certain cards and do they both have to be the same?
