Hi I have been told in the shout box that with out games officially supporting SLI they won't benefit any from having a second card in the computer. After some research I found out Need for Speed Most Wanted 2012 doesn't have SLI support along with the Dolphin emulator. After removing my second GTX 770, Dolphin started to stutter and Need for Speed Most Wanted dropped down to an atrocious 20 FPS. So whats true? Thanks EDIT: I guess NFS Most Wanted does have SLI but didn't have it activated... who knows
I think the answer is yes and no. I'm by no means a PC master race fanboy but my understanding is it all comes down to drivers and profiles. It's primarily down to developers to write their games to work with current architecture. If a developer doesn't write the game to officially use SLI then u may get problems, but then u may not. As new drivers get written this may correct it or a game profile may work. I have used 3rd party patches to patch nvidia drivers to run SLI on an Intel chipset that doesn't officially support SLI. So if u can find the right 3rd party driver patch or profile then whether the game 'officially' supports SLI or not, is irrelevant.
why not use the 2nd card as physx card rather then sli? personally i've always wanted to play around with physx and sli to see which makes more of a difference when i comes down to fps. sadly i've never had any decent gfx cards to do so with.
