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.
SLI and Crossfire
NVDIA SLI and ATI crossfire
Yes, check to make sure who makes the card. Such as Nvidia or ATI. Then check to see if your motherboard is [nvidia]SLI or [ati]CROSSFIRE compatible. For SLI you need 2 of the same video cards, ATI doesnt have to be the same. www.nvidia.com www.ati.com they should have helpful information on how to install there products.
The two types are integrated and discrete. Discrete video cards are much better than integrated.
Anywhere from 750 to 100 watts if they are high-end video cards, like a NVIDIA 460 or ATI 6870.
In a standard deck the probability is 0. There are not two, but 26 cards of the same colour.
Yes as long as your motherboard supports it.
Yes you can.
why not?! :)
You shuffle the deck. One person takes two cards off the top. The second player does the same. Add the digits. Whoever has the most digits wins the cards. Keep doing this until the you run out of cards. Whoever has the most cards wins.
numerators you add, denominators you leave it the same
Yes, it is possible to have two debit cards for the same account. This allows multiple individuals to access and use the funds in the account.
