There is a good article at Tom's about SLI, with some interesting conclusions about the changes recently with the Nvidia centric mode of using two cards or more to render faster and/or better. There will be an article on Crossfire also coming up.

It is dated april 27, 2015 at 12am, who knows if that is noon or midnight? Garwsh, and gee-wizz. IF there is a kind moderator with a bit of free time, I would appreciate a hand with this so our friends like me can find this article easier.
I was not aware that the 900 series of GTX Geforce cards are unlike previous generations in that you have more stringent rules for using two cards in SLI, for instance, I used two 560ti GTX cards in SLI before my purchase of a 970 GTX, and had no problems with them being different brands, different speed GPUs, and different speed VRAMs, it just defaulted to the lower of the two card's values for both, however, now they need to be identical, apparently for the 900 series. I achieved an unproven approx 90% scalability using educated observation.
I had no optical problems at all with the two 560ti cards in SLI except a very minor four pixel thick horizonal transparent line that appeared about every ten to fifteen minutes and disappeared within 1/6 second. I had thought they were using paneled SLI where the top and bottom are shared between the two cards, but they are using every other frame type SLI, coulda knocked me over with a big feather. Live and learn.
They also touched on the fact that might put a smile on i7 user's faces, that the cpus became saturated and bottlenecked the SLI process at some times. Me looky now at i7K series for a sub for my i5 3340P at nonK-OCed 3.7Ghz, heh, eventually, since I plan on adding a GTX 970 to use SLI when I get that 34" curved screen 1440P (dreaming). I had always been fed the line that the i5 cpu was within 85% of benefit that an i7 has, for gaming, course that may still be true for one card, but still......
