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

Features
By published

Back when GeForce GTX 780 sold for $650, slinging a bunch of 760s together looked like a great deal. Now that the 780's down to $500, is there still value in going three-way SLI with GK104, or are you better served by a couple of GK110-based 780 cards?

Results: Metro: Last Light, Medium Details

Nvidia's GeForce GTX 780 continues its charge through Metro: Last Light at our medium-quality settings. SLI scaling looks fairly weak on both the 760 and 780.

A single GeForce GTX 760 is perfectly capable at 5760x1080, dipping below 30 FPS in only a few frames. Adding cards raises the average frame rate slightly, but also causes minimum frame rate to drop under 20 FPS.

One GeForce GTX 780 is faster, but still not fast enough for Surround at 5760x1080. A second 780 imposes even lower minimums as it simultaneously bolsters the average frame rate.

    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.

    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?
