Rtx 2080 nvlink for 3440x1440

Hey guys, with 2080 ti prices pretty much stuck at $1600 I'm considering running two 2080's with nvlink but I haven't seen any benchmarks for the two cards at 3440x1440. Wondering if any of you nice people that had access to two 2080's would be willing to run a couple of benchmarks. Also if you have found 2080 nvlink benchmarks for 3440x1440 already drop a link please! Thanks in advance!

Patience is a virtue, especially in this case. I ran into several issues with SLI in the past. Some games just flat out do not support it.

Just look at benchmarks for 1440p and 4k and you will fall somewhere in between.  Plenty of Youtubers have posted videos about the RTX cards in SLI.

I don't see any need for SLI on 3440x1440p, given the 1080 Ti alone already could run it pretty fine, specially when targeting 100fps.

2x 2080 with NVLInk would be probably couple % stronger than 2x1080ti in SLI so at this point you need to consider whether your CPU can handle that. 

 

You can go on ultra on basically anything you want and reach 120FPS easily - games like Witcher 3 or Tomb Raider for instance will be no problem. If you see that you are reaching beyond monitor's refresh rate (since you mentioned ultrawide, I have strong suspicion that you will not have more than 120Hz refresh rate), consider enabling DSR in NVIDIA Control Panel and start playing at 4213x1764.

 

So yeah, if you can't find any benchmarks or videos just try to find some 1080ti SLI in 3440x1440 and then maybe adjust the results by about 5-7%.

Yeah I just thought I might get more performance out of the two from nv link, which seems to be alot better than sli

I was thinking of doing the 9900k but i can save a decent chunk of change going 8700k and really not seeing that much of a performance decrease.  But for 2 2080's or ti's it may be worth it

If you're running a graphics card with two die on each pcb... Is it dual or quad? :D

Honestly speaking, unless you intend to game at 4K at max setting plus 60fps or higher, I don't see a need for an SLi RTX 2080 setup. I have an RTX 2080 Ti and a VEGA 64, and I think I hit the sweet spot in terms of my gaming experience with an UW 21:9 3440x1440 display. My GPU's can dle a vast majority of games at max setting and still get >60fps......it gets a little dicey when you up the res to 4K.

 

I've been putting my VEGA 64 thru its pace with Metro 2033 Redux and Last Light, Doom, Crysis, Crysis 3 and it can handle these games at max or near max setting, I'd get a min of about 50fps and higher for the more graphically intense games like the Metro series. With my Freesync monitor, it's pretty smooth going. My RTX 2080 Ti is also hooked up to the same monitor and it powers thru games like a hot knife thru butter at 3440x1440.

 

The most GPU count I'd ever tried is a HD3870 x2 + HD3870 setup from years back, Tri-Fire goodness, though it did scale negatively on quite a few games, but when the game has CF support (usually up to 2 GPU's though) that Tri-Fire setup was bada$$. IF you wanna go more than one GPU for gaming, stick with two GPU's at the most, SLi and CF support is usually up to two GPU's only.
