If I put two AGP Cards (one Nvidia and one ATI) will it work or boost my graphics performance in any way?

Question

I have once Nvidia AGP card and One ATI AGP Card and two Slots. If I put both in then will it boost my graphics up or not? Or will it bug/crash my system? Just tell me what it would do lol Thanks so much!

Answer 1

Your computer will have a hardware conflict. It won't know which card to use, and may not work at all. It won't boost your graphics to use two cards. Just get a really good card with a large amount of video memory and only use one.

Answer 2

There really is no way to do this. No computer has *two* AGP slots so before you even worry about the conflicts you would get if this was possible you hit the problem that you won't have two AGP slots in the machine. You will very likely have multiple PCI slots for 'normal' cards (like network, sound, etc) but you will only have a single AGP slot.

Newer motherboards take advantage of a technology called SLI to allow you to put two gfc cards into the same machine but (a) this only works for PCI-Express video cards, not AGP and (b) both video cards must be the same 'type' or it won't work at all. More info here:

Answer 3

What kind of PC do you have? It is almost unheard of to have two AGP slots in a PC, and no technology is designed to use two AGP cards, so you won't get any boost, you'll just be able to connect more monitors. Do you mean you have two PCI Express slots?

If you have two PCI Express slots, and use SLI (Nvidia) or Crossfire (ATI) cards, you can have substantial performance boosts. To see any performance boost, you will probably want to use as similar video cards as possible. If possible, use cards with the exact same chipset, if not the exact same card. You can't really mix Nvidia and ATI.

Answer 4

There is no TWO AGP slots in one board; 1 AGP + 1 PCI is more likeit; but it will not boost graphics performance, one card constitutes one video subsystem, 2 means 2 separate subsystems.

Answer 5

Unless you have a second monitor, you won't have any boost. In fact, having two different cards could cause real problems. If you don't have 2 monitors, pick the best card of the two and stick with it. I've had good luck with both Nvidia and ATI cards.

Answer 6

Never saw any computer mainboards with two AGP slots!

I can run three dual head PCI video cards, and six monitors, with USB keyboards, and six USB mice, for six users, in Linux or BSD. Great for cruise ships, libraries, classrooms.

But, being that I get Compaq 1.5 Ghz systems for FREE, in a non-profit, to setup churches, and private schools, it is lots cheaper to just put one Linux (Fedora Core 5) system per student.

I often run multiple network cards, in pci slots, so that I increase my transfer speeds to near Gigabit throughput, running a small cluster like a Beowulf, on my home network. I get the 100kbs ethernet cards for about $1 each, on ebay.

Answer 7

No. It wont work. You can use any one of the AGP Slot in a mother board. If you want to use only one, you have to disable another from the motherboard.

Answer 8

maybe you got two video card one nvdia and ati radeon, but you can put in in your motherboard at the same time, there is no way , you could do that, because there is no mother board who can supported two agp slot at the same time, even there is , it wil be a conflict of interest.

Answer 9

wont boost anything, may or may not have a conflict will prob be prim and sec vid card. but there should only be one AGP slot on your computer making it impossible to put to put two in

Answer 10

Yes you can settup multible display and use two graphics cards, but only for more then one display, two graphics cards and a single display wont work
