SLI Scaling: Can Three GeForce GTX 760s Beat Two 780s?

Results: 3DMark And Far Cry 3

Why is there a synthetic test and a real-world game on the same page? All of the cards I'm testing were on loan. Embarrassingly, all of the cards in today’s comparison were on loan, and I figured out that some of my data was missing after sending them back. I could have scrapped the piece altogether, but because some readers are probably only looking for comparisons between three-way GeForce GTX 760s and two-way 780s, I figured I'd simply march on with a couple of holes in-place.

If the scaling we see in 3DMark carries over to any of our real-world games, the cheaper cards could have trouble proving their value in three-way SLI.

Although I was missing results for two-way SLI on the 760s in 3DMark, it was the three-way numbers that I lacked for Far Cry 3. I'm keeping the charts anyway for the folks more interested in comparing a pair of GeForce GTX 760s to one 780.

Far Cry 3 suggests that two 760s is the way to go for around $600. This would have been a pretty definitive win if the GeForce GTX 780 were still a $650 card. Perhaps that's what Asus had in mind when it started designing its latest dual-GPU endeavor. That board's 2 GB per GPU would likely limit performance at very high resolutions and detail levels, but at least a pair of the GeForce GTX 760s on which Asus' solution is based would at least have sold for the same price as GeForce GTX 780.

    Very interesting article. Would have been great to have the GTX 770 SLI'd in there for comparison :).

    Agree with the conclusion totally since after the price drop on the GTX780 I stopped recommending dual GTX760 over the GTX780.

    770 is the 680 with more hz... 760 is a new nvidia product is a 660ti with more muscle. 760 = 670 in power

    there are some major fps drops in the sli configurations on bf3, wonder why? did that happen on the single monitor solution? and in other games? crap like that is why i switched my sli config out for a better single card.

    would've been interesting to see the 2GB cards in SLI also

    I checked and found 1 stuck frame on the GTX 780 SLI at 1920x1080. It lasted far less than a second and dropped FPS from 200 (capped) to 54.

    Yes, but the problem is that it's hard to find six cards laying around (three of each), and we quit buying 2GB cards for 3-way SLI a couple years back when they started running out of memory at 2560x1600. It got worse in Surround mode.

    I noticed in Tomb Raider that 780 SLI was broken, yet 760 SLI worked well. 780 SLI had worse scores than a single 780 using Surround setups, yet the 760 SLI worked with surround setups quite well. I wonder what is up with that.

    weird sh!t sometimes happens with multi-card setups. i have owned both crossfire and sli in the last couple years, and now i'm dead set on single card is the only way to go, only takes one game not to work properly to ruin your day. Multi card for me, is only for when the best card available isn't powerful enough for you, or maybe second best card as the best is often overpriced ridiculously.

    Waiting for Maxwell. Prices on both sides need to come down. Best for single GPU's was $500 with dual gpu's being double the price, i miss old prices.

    How about 2x 760 v 780 ti and 3x 780 v 2x 780 ti?
