Do Two GeForce GTX 680s Beat Three GeForce GTX 660 Tis In SLI?

Test Settings And Benchmarks

We tested Gigabyte’s GeForce GTX 660 Ti samples in both two- and three-way SLI, and its GeForce GTX 680 4 GB samples in single-card and two-way SLI configurations.

A reference-clocked GeForce GTX 680 2 GB helps us define the advantages of Gigabyte's overclocked boards with twice as much memory. Don't worry, the differences between clock rate and memory capacity will become perfectly clear as we work our way through the benchmarks.

    off topic:

    when titan's review comes out?

    on topic:

    frankly i'm no multi gpu nor multi monitor user. but for the green camp if you want multi monitor gtx 660 ti 3Gb is a good choice if you want the cheap option. if you want more horse power while still on the cheap side then 7950 is the answer. (the latest game bundle from amd might also lean some people to buy amd cards)

    From my own experience I would rather go with 2x 680 as dual sli scales very well on about _all_ titles while tri/quad sli can be more of a gambling in performance - For titles where all the cards scale well its sure nice as hell - Where it does not you can even loose performance by adding a third/fourth card (even thoo that scenario gets less and less frequent).

    Nice review, makes me consider taking 3x7950 instead of 2x7970. Would equal in price due to sales that are going on. But, maybe grab a Titan? I hope to see another review in 8 hrs featuring Nvidia GeForce Titan.

    Not the point of this article, but i noticed that a single gtx680 is a complete beast at 1080P.
    Also, it would have been interesting to see the CPU usage during the tests.

    Edit : A repeat of this article with the HD7000 cards should be performed, specially after the 13.2 driver are released.

    Yes same review for HD 7000 series should be given. Can't wait for that.

    I'd still go for a GTX 690 Hydro Copper. Overclock it and pwn while only taking two slots. SLI configs which take up all your slots seem highly inefficient and unappealing.

    Why do you say "higher/lower is better" in some graphs? Which is it - higher or lower?
