SLI 770's or single 780 Ti?

I am soon buying a new monitor, either 1440p/120hz(ROG Swift) or a 4k monitor. Which GPU setup would get me the best results?

Nothing less then a 780ti for 4k if you get the new $700 4k monitor. I'm using a 770 4gb and I'm running bF4 maxed out with AA at 2 times and low for the other. and I pull about 38-60fps at 1440p. So I'm kind of in your position as well. I'm torn between selling my 770 and getting a 780ti or just buying another 770 4gb to get myself to a stable 60fps. I'll get more performance from the two cards but I also take the risk of having issues with sli instead of a single card solution. It's a hard decision, since the damn things cost so much damn money.

If you're looking to play high graphics on a 4K monitor you should know this - to be able to run your games on high graphics with 60 fps you need SLI 780 and above OR Cross 290 and above.

Aside from those things you should know your MOBO should support it and also having about 1000Watts PSU.

Now for your question which is better, hands down SLI 770 because even SLI 760 surpass a single 780ti performance.

Wait with the 4K monitor, needs more time... And HDMI 2.0

Go for SLI GTX 770 4GB it will be faster then a single 780ti and have a gigabyte of extra vram which you will defiantly want gaming at such high resolutions.

I'd just get the single 780 ti along with a 1440p monitor, and upgrade to sli when it's actually needed. There are no games out right now that won't play great in that setup, and you probably won't see any games this year (likely most of next year as well) that can't be easily handled by a single 780 ti, so don't freak out about sli. If you have a 770 already, go ahead and sli now because it will save you money for other things. There is no reasonable setup that would allow you to comfortably run the most graphically demanding games out today at 4k. I would wait for Maxwell before I even start thinking about 4k.

So basically, when in doubt, always get the single strongest card solution you can afford, BUT if you already have a card that when in sli could out-perform the single strongest card you can get, use sli.

Also, it depends on what you want out of your system, and what do you care about the most (e.g. graphics, fps, power consumption, etc.).

i asked this same question about a month ago. I would say wait a few years. Im playing in 1440p until january/february 2018. Then when 4k have matured and we have single gpus which will kick ass at that resolution im buying one. And btw dont go for a cheap 4k tn panel. Go for a proper PLS/IPS one.

As a lot of people are saying, I would wait on 4k for atleast another year or so.

This thread was about choosing a GPU, not a monitor. but thanks for all the input guys/girls.
