Following a thread that I've posted yesterday I learnt that if you SLI two cards you get more performance only if the application is designed to work in a SLI configuration.
How that works? What happens if I have a SLI configuration, but the application does not work in SLI? Will I be using only one card while second stays idle? Is there a way to "force" an application (game, photo or video editor, whatever) to recognize my second card as well? Or, how would I know if the application uses only one card or both?
(I am particularily speaking about SLI-ing 2 GTX285 vs. having 1 GTX295)
So the world's fastest card is built on a GTX285 GPU platform. And if I think, if you quad-SLI a GTX285, you get somewhere around that price too. This says a lot. A lot of things got clear for me now -- thanks!
