Hello people of tech talk
Currently I have a nvidia 4800se 8x agp card which has duel head and now I want another screen so I can have three is it possible for me just to buy a pcie graphic card and use that aswell?

AGP x8 and PCI express graphic cards are two different thing.
IF your motherboard is enabled with PCI express, buy PCI, and AGP 8x/AGP 4x/AGP motherboards, then buy the graphic card respectively.
PCI express type support up to two graphic cards, while AGP 8x only can have one installed on the motherboard.

Secondly, a user with an appropriate operating system can use several PCI graphics cards (or several PCI graphics cards in combination with one AGP card) simultaneously - to give many different video outputs (for the use of many screens). This cannot be done with AGP cards, as very few (if any) motherboards are equipped with more than one AGP slot

Well, some people say PCI while some say PCI Express. But the exact one is PCI express.
en.wikipedia.org says true.

I don't know if you can use both cards at once, i highly doubt it..

AFAIK: There are very few motherboards that have both AGP and PCI-EXPRESS slots, and I don't even know if you can use both at the same time.

If you want to, you can go out and buy a PCI (no express) video card and add it to your system, to power your third monitor. This is what people had to do before the multiple head cards we have now were standard. I would suggest getting an nvidia card, because then you have fewer driver problems from using different types of cards.

Now if your motherboard supports PCI-Express (which I'm 98% sure it dosn't, since you have an AGP video card) and it supported using 2 graphics cards then yes, you would want to buy a second PCI-E graphics card.

The important part is PCI is not PCI-Express and a PCI-E card is not backwards compatable with a PCI slot.

hmm not sure if this is relivant to pci express but wikipedia says

Yep, pretty much all right, you can use multiple PCI cards along with your AGP card, but there are almost no motherboards that support multiple AGP cards.

Everybody stop right there!

- There are two different PCI formats: the old PCI, and the new PCI-Express.

- No motherboard I have ever seen has both AGP and PCI-Express.

- Further to this, I highly doubt that AGP and PCI-Express will work side by side.

- Older motherboards have AGP and PCI, and a PCI card will work alongside an AGP card.

Edit: Dammit, got beat!

What are you on about? Those are both two different technologies.

thanks everyone , I think ill just go buy another normal pci graphic card then (before i was going to buy a new mobo and stuff i just assumed they would have agp on them)

-dt-: Yep, thats probably your cheapest and best option. Definatly cheaper than buying a new mobo.
