But I have seen people complaining with kepler that they had to drop their OC quite a bit when running multiple cards. Not sure if drivers are helping with this or not. Maybe someone running two cards will comment.
I agree but I wonder it has to do with the "lottery" of performance. What I mean is, I don't think it is the inefficiency of the SLI scaling but the fact that almost no two Kepler cards are the same in terms maxed absolute stable core and memory OC. We all know that if you link the cards, then the lesser card will be the one holding back the SLI. I think the best way to prove this out is for someone who has SLIed keplers to downclock them the factory OC. Run benchies against either card and the SLI and see what the real inefficiency is. Maybe I'm all wet.
If someone is willing to send over their GB 670 WF3 to me, I'll be willing to test this! Brettjv / DADDY / g00s3y
