SLI + Ultrawide Monitor

[alexisvx]

Hi all,
I am buying the Asus PG348Q (IPS/3440x1440/100hz). I currently have a GTX 970 and thinking of also upgrading my GPU along the new monitor.

The question I have is whether I should go for SLI or for the GTX 1070 (I can't afford the 1080).

I have read about SLI VS 1070 in terms of benchmarking etc and for my needs these options are the same. In terms of cost, I would much rather go for SLI but I am not sure how it will perform for this monitor.

Thanks

Get the 1070, performs far better, and SLI support & scaling is all over the place.

Hi alexisvx,

A single card will always be a smoother experience over multiple cards. I'd definitely recommend a single 1070 over 970s in SLI. Also, because the monitor has a high resolution of 3440x1440 it means you'll reach the 3.5GB VRAM limit of your 970 which will cause stuttering and other issues (970s aren't true 4GB cards if you weren't aware). SLI doesn't stack the VRAM so you won't have 7GB (8GB) VRAM.

Hope this helps,

Leemon

So would you say that SLI would be problematic and cause issues with the display?

Higher resolutions need more VRAM, SLI does not multiply or increase the VRAM. So the 1070 is better.

Thank you all for your answers, I'll go with the 1070
