GTX 980 SLI needed for a Asus G-Sync 144mhz monitor?

[davidst99]

Hi,

I have two GTX 980 in SLI. I traded in my 4k monitor (I didn't care for the quality) for the Asus PG278Q G-Sync 144mhz monitor. Do I still need two GPUs for this monitor since it's only displays at 2560 x 1440? Thank you.

I would like to use the new DSR feature from Nvidia but it does not work in SLI and G-Sync. (At least for my monitor)

Disable SLI and see if it's acceptable is what I'd suggest.

:thumbsup: OP has all the hardware to do the testing for himself. I'd think you'd still get a lot of benefit from SLI. I needed 2x970's to hit 100fps+ in Shadows of Mordor. If you want to see the benefit of 144hz, it'll likely be needed.

Thanks for the reply and suggestions. I disabled and do notice when I run a game at the higher settings like I do with SLI it slows down a little but I G-Sync helps out a lot with that. I just wish DSR could work with SLI+G-Sync.

I would keep SLI and turn up the settings

What is your opinion of gsync so far? What games are you playing?

I haven't heard anything about this before. Does anyone know if there's been an SLI review done with a Gsync monitor?

I notice that the games run a lot smoother. There's no skipping. I'm not sure if that's related to the G-Sync or running 144 Mhz.

I run a 120hz 1440p (Overlord Tempest) with dual OC'd 780's, and it leaves a ton to be desired. I don't think i'd be completely happy with dual 980's.

I have the same display with 970 SLI. I'd keep the 980 SLI even at 1440p.

Gsync works with SLI, but DSR does not.

DSR works with SLI, I use it all the time. What doesn't work is MFAA, at all with SLI. I do not know if DSR + GSync works though. I don't have a Gsync monitor.

Though with a resolution of 2560x1440@144hz you might not get much benefit from DSR. Depends on what results you're looking for I guess.

Gsync works with SLI, but DSR does not.

Everything works with G-Sync on a single card. With SLI, DSR works but NOT if a G-Sync display is connected. It doesn't matter if G-Sync is disabled or not, just having a G-Sync display connected is enough to disable DSR on SLI. Really annoying limitation from Nvidia.

So to recap: SLI + DSR = OK, SLI + DSR + G-Sync = no go.

It seems that Nvidia has really dropped the ball on getting DSR and MFAA working properly with SLI and G-Sync as there hasn't been any news or progress on the matter for over 6 months now.

My Titan X works pretty darn well at 1440P, I'm sure you'll be fine, though I am not a big fan of multiple cards.
