You can install two video cards in a motherboard that has two 16x Graphic card slots available. If they are SLI or Crossfire compatible, they will work together and both total up your graphics memory. If you have graphics cards that are different, most likely one will be disabled or they could have drivers issues. It really depends, you could just put it in and try.
Yes you can use an ati video card in a sli motherboard, however you cannot put two ati graphics cards in that motherboard and run them in sli. As far as putting one in and just running it single your ok. You would need a motherboard that supports Crossfire to run two ati graphics cards together.
If they will physically fit, then yes you can. How much good this will actually do depends on the specifics of the cards in question. Some cards can be "combined" to give a higher graphics processing power; some cards cannot, and having two cards will simply allow you to run two monitors. In some cases, adding a second card might even result in one of the cards being disabled.
The most advanced consumer video cards are the nVidia GeForce GTX295 and the ATi Radeon HD 5970. Most gaming computers will run two of these in SLi (nVidia) or CrossFire (ATi) format, with two on one computer, or even four linked together for dual-SLi.
Older cards such as the geforce2 and the riva tnt2 should work. Any card that will slot into an AGP slot should work, just make sure that it can run in 4x mode (Modern day AGP video cards run in 8x mode but some will also run in 4x mode)
The two types are integrated and discrete. Discrete video cards are much better than integrated.
Video cards are expansion cards that generate output images to a display. Yes, video cards and graphics accelerator cards the same thing.
Cpmare it's sepcs to the specifications on the cards box.
Typically, the most powerful and most modern gpu your computer can run. The two major brands of video cards are ATI and Nvidia.
Anywhere from 750 to 100 watts if they are high-end video cards, like a NVIDIA 460 or ATI 6870.
Most video games can run on the graphics cards provided on the computer. If a different graphics card is needed it can be easily purchased online or at a local technology chain store.
Yes as long as your motherboard supports it.
It is certainly possible, though other things may become problematic as well, as video cards need something to run them. Also, even if the video cards are not seriously damaged, extended use cannot possibly help their performance.
