2 old card SLI better than a new one?

HI wondering:

- for 3D modelling, VR and a bit of gaming, is it better to:

1- Add a second Nvidia 1080 (8Gb) with SLI

2- replace with a 2080

 

Thanks for your help on this

Somehow, despite the fact that it seems like the perfect idea, SLI is garbage for VR. You'd see benefit in 3D modeling, but all gaming applications will by and large be benefitted by a good single card.

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k (won) - EVGA Z370 Classified K - G.Skill Trident Z RGB - WD SN750 - Jedi Order Titan Xp - Hyper 212 Black (with RGB Riing flair) - EVGA G3 650W - dual booting Windows 10 and Linux - Black and green theme, Razer brainwashed me.

Draws 400 watts under max load, for reference.

 

Linux Proliant ML150 G6:

Dual Xeon X5560 - 24GB ECC DDR3 - GTX 750 TI - old Seagate 1.5TB HDD - dark mode Ubuntu (and Win7, cuz why not)

 

How many watts do I need? Seasonic Focus thread, PSU misconceptions, protections explainedgroup reg is bad

Personally, I'd sell the 1080 and buy a 1080Ti. It's the best-value upgrade if you want more performance in the tasks that you mentioned.

SLI for VR is really bad, and still some games don't support it. Better get 2080 (For gaming but for 3D modeling 1080 in sli is better)

It's that huge of a jump from a 1080 to a 1080 Ti/2080 personally speaking that would justify the hassle, I'd try to sell it and keep saving and try to go straight to the 2080 Ti personally.

 

Turing is noticeable better at 3d modeling by the way, nVidia seems to have fixed that weird gap Pascal had against AMD's Vega on these hardware acceleration workloads.

Thank you so much for your advise. That is really helpful in guiding my decision.

No sli for vr but given how little a 2080 is better than a 1080ti I wouldn’t do it. A pair of 1080’s destroy a 1080ti.

When they work they do. Not every game works with SLI.

Those are the games I play. Have been since i started pc gaming. Obviously if you play a game that’s poorly optimized you shouldn’t be asking about sli.

Just assuming that the OP will play games optimized for SLI (which is becoming more and more of a niche) is poor practice.

Make sure to quote or tag me (@JoostinOnline) or I won't see your response!

If you asked me this question 5 years ago I would have said go for the SLI but in recent years Nvidia has forgotten about SLI. The new 2070 doesn't even support it (though only reference PCBs have been tested) so it's a kinda dead technology. If want you are doing is solely work based and the program can take advantage of multi GPU scaling then find a cheap second hand 1080 and a high speed bridge and Run SLI. If you are doing VR then go for the newer, single card as you will get soooooooo much more stability and support! 

 

Hope this helps

Same with assuming they won’t. Just a guess based on lack of info. Which is the common trend on here. Just as the youtubers tend to do.

OP said 3D Modeling and VR are primary.  SLI blows for these uses.

Probably because the OP has not worked with SLI before.  SLI does nothing or is actually a detriment for those use cases.

Now he knows. And that’s where priorities come in.
