Does it make the computer graphics better if you put multiple pci graphics cards?

If I put a 128mb graphics card in the agp slot and 3 64mb pci cards in the pci slots would it add up and make the graphics any better? Or would it just cause a problem like overheating?





What exacly would happen?

Does it make the computer graphics better if you put multiple pci graphics cards?
No, only one graphic card will be utilized at the time. You can select the graphic card options from your hardware list, but only one can work. The graphic RAM will not add up.
Reply:No, it won't do anything because your computer will only use one of the video cards (whichever your cable is plugged into).
Reply:There are a few things that you are going to be taking into account here:





1. How many monitors are you going to be using?





- If you are only going to be needing one monitor, then us one video card (unless you have a graphics accelerator card which plugs into your video card and the monitor plugs into it.)





2. If you are going to be using multiple monitors, how many?





- If you are going to be using 2 monitors, check and see if you have a video card that has multiple video outputs (DVI or VGA - don't useS-Video or Composite video because they don't give a clear picture), then use just that card and it will be faster because the application used to control the card will work better.


- If you are planning on using 3 or more monitors, use three or more video cards and try to find a program the will help to incorperate all three into your desktop.





3. If you are only using 1 or 2 monitors, do some research on the graphics chip for each of your video cards.





- If you have a 128MB video card and a 64MB video card, the 128MB isn't necessarily better! You have to check the graphics chip and the memory sharing capabilities.





- It is possible to use a 64MB card with 256MB shared memory (make sure that your driver software will allow you to do this) and get more out of the card than with a 128MB with the same speed graphics chip.





4. Do you have only PCI cards and slots or do you have AGP or PCI-Express?





- If you have a PCI-Express slot in your computer and a PCI-E card, use it first, if you have an AGP slot in your computer and an AGP card, use it instead, and if you only have PCI cards or PCI slots, then use the PCI cards.








IN SHORT:


Don't use multiple PCI video cards unless you are going to use a bunch of monitors, and yes it will slow down your computer, relatively.
