GTX 970 SLI to GTX 1080 @ 1440p?

[SyphonSystem]

Can't seem to find much comparing these setups. I would like to get more out of my system at 1440p.
-i7 4790k
-16 GB DDR3
-GTX 970 SLI

gtx1080 would be better for 1440p

gtx 970 is great for 1080p, but at the higher res you will want more vram and a faster single gpu
sli doest add more vram

In a nutshell you will get:
- twice the performance if SLI isn't supported
- twice the vram
- and half the power consumption

A single 1070 / 1080 / 980 Ti will certainly help to eliminate all the issues SLI comes with, at around the same performance, or better.

Sell your GTX 970s and get single GTX 1080, this card is great for 1440p.

Looks like that is what I am going to do.
Thank you!

Honestly if you have GTX 970 SLI don't bother upgrading for a few more generations.

no true : games are increasingly getting VRAM hungry and the GTX has "only " 3.5Vram not enough for the comming games. Look at Mirrors Edge Catalyst Hyper settings -- a GTX 970 even in Sli performs under 30 fps.. expect to see that kind perfomance in near future titles with the GTX 970 sli.. Im upgrading to GTX 1080 very soon because of this.

DX 12 will allow VRAM to be additive in SLI meanine 4+4=8GB.

Also if you have enough system RAM they can share that as well.

SLI will be good for a while yet. But a single card is always better (SLI still has issues). 1080/1070 are really the first cards aimed at maxing out 1440.

Thats true but in the meantime there are 0 games who are stacking up the Vram ( or at least none atm i am aware of ). I really was excited when i learned about this feature but i think it takes a good year or 2 before we ( sli users ) could harness that power.

Correct a single card has always my preference above 2.

SLI is amazing, but if a single GPU is more powerful than 2 970s, go for the 1080.
The 970s should be able to sell for a decent price
You may want to clean them up a bit, and possibly change the thermal paste on them before selling though.

I upgraded from 2x gtx980's to a gtx1080 and all my games run much better!

While on paper 2x gtx980's seem better, i actually get higher framerates with a single 1080 in games like GTA5.

When it comes to SLI, Bandwidth and Lanes become a factor
And more communication between the system and the GPUs are being done on SLI than with a single GPU in a sense.
