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?

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.

Why is it that the graphs show 1 760 at 100% price, 2 at 200% price, and 3 at 400% price? Should 3 of them be 300% price?

Thanks for pointing out that the last page charts were based on QUAD pricing and Tri performance! Fortunately, knocking the B out of FUBAR is my specialty :p

I am sorry, but it is quite evident that what we are seeing here is a lack of support and bad quality drivers. 3 760 GTX result should have been more in the line of Tomb Raider results. Funny to see NVIDIA fanboys cry over ATI bad drivers, but at least a third AMD card generally ends in better framerate... unlike what we can conclude here.

Funny, my single MSI 660 only runs 5fps slower than the single 760 in all of those tests. I must have a freak of a good card.
December 23, 2013 8:51:42 AM

Why no 770 I feel 4 x 3 gb of gpu ram is over kill and it is just a 30-40 buck price difference between the 770 2gb and 760 4gb. The 770 would have been a better buy.

Why not test this on COD Ghosts? Oh that's right, its been out for 6 weeks and it still does not work right with SLI. All the flickering sights and trees are making me nauseous.

Funny, because the article was written about six weeks ago :)  We had a flood of launch articles in November dalay a bunch of non-timed articles by 4-6 weeks.

I'm curious if SLI (or xfire) is ever really a good value when you consider things like game support, time invested, mental sanity, and so forth. I mean how much savings is that much aggravation worth? Just because I could save money by using old newspapers instead of toilet paper doesn't mean I should.

In the case of two way SLI, there is rarely aggravation. It just works in almost every game. The ones it doesn't work in usually don't need SLI to get good performance and you just don't realize it isn't working.

That said, a single card is a better way to go, IF you can get that performance from a single GPU. If you want more performance than a single GPU can give, then go with two.

IMO, SLI should only be done with higher end GPU's, when you want more performance than a single card can give.

Man those numbers are amazingly close and value wise three GTX 760s cost just a little more than a single Titan. I'd still take dual GTX 780TIs any day of the week though!

nVidia's wizing up....

580 sales tanked cause two 560s was 40% faster and 20% cheaper.
Two $150 650 Ti Boosts paired up edged any single gpu card waaay more

Tho over 75% of the builds I do are SLI/ CF, I have however always had trouble making a case for Tri SLI and Tri CF is not a place many will venture.

I found that the answer to the title was obvious. 780 vs 760, 2304 vs 1152 shaders? One has literally twice as many, and 2x2304=4608, whereas 1152*3= 3456. I know this oversimplifies the question, as number of shaders aren't everything, but when comparing shaders, even when considering the higher clock rate, the 780's will win. Even with perfect scaling, the 760's just don't have the computing power. 2 770's vs 3 780's would have been more interesting; same number of shaders(approx), but 770 is clocked much higher, and the 780's have better scaling. OC'd 780's would put up a very fair fight, I'd say.

Just buy a 780 ffs.And how can you have over 120 fps at 1920x1080? I can only get 60

Is your V-Sync on?

Vsync is on, should I turn it off?

That depends. Without V-sync, you'll have tearing, but have lower latency. Both are advantages, both settings have disadvantages, until G-sync becomes available to you.
December 24, 2013 2:49:59 PM

ha yeah time will come and hopefully will get a decent monitor. correct me if I'm wrong: everybody tells me I can't get over 60 fps because my monitor is 60hz, is that true? can I still break the 60fps barrier?
December 24, 2013 7:03:34 PM

Excellent write up and I personally can vouch for the validity of the 780's in SLI. They are unbeatable force and can even power Battlefield 4 on Ultra setting while taking full benefit of my 144 Hz monitor.

FPS are how many frames the GPU creates. Your refresh rate does not change that. However, your monitors refresh rate tells you how many times the images on the screen update. If you have more FPS than your refresh rate, the monitor refreshes may contain more than one frame blended together, with a tear between them.
December 26, 2013 5:24:20 AM

exactly what happened when I disabled Vsync :-) So you are forced to have Vsync on and restricting your GPU because your GPU can pull more data than your monitor, that sucks a bit. but many people say there is no difference above 60 fps so do you think its worth spending like 300 quid on a monitor?
December 26, 2013 5:03:18 PM

One thing in the article that i usually observe. The price of getting dual video cards doesn't really work well against the price of a single better video card. I've seen that for years now, even though i've bought motherboards for the possible addition of a 2nd video card.
Would be nice if they did an article for that. Dual cards that are cheaper and faster than a single newer video card. Wonder what the results would be?
January 13, 2014 10:29:49 PM

yes it could beat .... but ... you should buy a 2 gtx 780 for SLI that would be ultimate
