performance ? Not Always , there are some games that dont take advantage of SLI or CrossFire , so you wont see a difference between 2 cards and 1 card in those games , but in games that take advantage of SLI or CrossFire , 2 cards will perform better than one....

but not needed. The 4850x2 is limited by its driver support from sapphire where the 4870x2 is supported by ati, but for both cards, if the game/application does not support xfire you are limited to one gpu. The 4850x2 on games that support crossfire should...
