Windows 7: i have an extra vid card, can i install it ?

i have a radeon hd 4890 vid card installed in my system, i also have an asus en8500gt silent vid card.I wanted to know if i can also install that card and would it improve the graphics ?

Hi, having 2 GPUs installed in your PC would theoretically improve the graphical performance of your PC, however in practice unless you have two compatible ATI or Nvidia cards and an appropriate Mother board you can't have two GPUs installed.

If your motherboard is the Asus m3a78-em, then you only have 1 pci-e x16 slot anyway.

Can you use them both at the same time? Yes. Will it improve anything? With those two cards not even if you tried real hard. For starters the HD 4890 is so far ahead of the 8500Gt in performance that it isn't funny. That and even if it was possible to combine the two it would work to the lowest common denominator, meaning the 8500 would drag the 4890 way down.

What you are thinking about is SLI or Crossfire; which only works when the cards are of the same make, model and specs (and as osholt said supported by the motherboard). About the best you can achieve by using both of those cards together is to run more than two monitors at a time if you were so inclined.

alright that you for the info guys musch appreciated.
