Second 1080TI

[idnok]

I'm guessing that won't happen.
Many factors are on the table.
Check UE, UNITY, FStorm, Octane (not the best example but anw).. All these are GPU based and most of them will support RTX in near future.
Plus, V-Ray is already spreading (check V-ray for UE), check project Lavina who knows what's next?!.
So no reason to try and monetize V-Ray for max that way... there are plenty of ways to be constructive and still on top of the game (which is exactly what they're doing).

I can see that I’m a bit late for discussion but the biggest bang for the buck here would be just getting something like 1070/1080 to run your displays and letting 1080Ti use its whole VRAM for VRay. I bet that your 3dsMax needs at least 5GB of video ram to display your scenes. that leaves just 6 for rendering on 1080Ti.

[Muhammed_Hamed]

His scene fits in VRAM without issues, so he is planning on using both cards in rendering.. If he ever runs low on VRAM, he can export a Vrscene and close Max maybe

[piotrus3333]

its like buying 24GB of ram considering Bobby’s scenes take 20. sure, it will fit just right but that’s just poor planning in my opinion. VRAM is still very expensive asset, and even 3GB wasted that way gives you two 1080Ti with 8GB used by vray (plus a slowdown on one card - viewport and rendering at the same time).
2x850$ will buy you 2080Ti with a lot left for something else. old 1080Ti still more than enough for viewport (do not know if both drivers would work fine together, for a piece of mind I run displays on radeon and rendering on geforce)
and 2080Ti is better option for future expansion, you just buy another one getting more ram and speed.

[idnok]

For ArchViz..there are zero to none scenes that will require 20gb of vram, if so.. means you're lazy AF (like me) drag n dropping everything you find online.
I Agree that a 2080ti is e better investment for future expansion (not only cause of memory but RT cores as well) but he is talking minor investment.
Having said that.. 1080ti its a solid card (speed and memory wise) and with the ability to save your vrscene, there's no memory loss from max.
Plus, the below image was rendered on a 1050ti (just to show that there's no real memory issue at least on ArchViz)

If you want to invest few Ks, than yes, as we said, 20xx would be the way to go, but that will require a better PSU, CASE, another MOBO with at least 4 PCIe slots and probably a custom airflow.

PS. There's a bedroom next to it that it is not visible (as i said lazy AF).

I don't agree
Getting a 2080Ti he will need 2x 8pin cables, which he currently doesn't have, so he will need to buy a new power supply and use it externally, read above..
Another issue we talked about in other replies above, is thermals.. even if the new card is blower style both his cards will throttle like crazy(the 2080ti produces a lot of heat, and his old 1080Ti is not blower style) .. Not to mention how loud these cards will be under load, check the pictures he posted for his setup..
This is why he bought 2 new 1080Tis, blower style and put his old 1080Ti on ebay

even 3GB wasted that way gives you two 1080Ti with 8GB used by vray (plus a slowdown on one card - viewport and rendering at the same time).

This is wrong on many levels, let me explain
Out of box you don't get 11 GB of VRAM on a 2080ti/1080ti in windows 10 .. You only get around 9 GB, rest is used by windows
And you don't just presume that his Max will take 5 GB of his VRAM, having a separate card for display performance is nice, but not necessary depending on the workflow really
The point of his upgrade was getting more rendering speed.. Having 2x1080tis will be much faster in rendering than a single 2080ti, this is not debatable really..
And again, having 2 cards you can always turn off one card during look dev, or even use the low priority option in render settings.. Then for final rendering he can use his 2 cards+2 CPUs
about Max taking up VRAM, he can render with standalone and close Max during his final rendering. This is actually way more effective for rendering animations
This tool by Alex Kurcera, he can render one frame per each render device(this can save a lot of render time in many situations)

old 1080Ti still more than enough for viewport (do not know if both drivers would work fine together

They use the same driver if you don't know.. Using an AMD GPU for display is a bad idea, you will need a Vega 64 to match the performance of a 1080, they are much more expensive, consume more power(some of them need up to 3x 8pin cables), produce more heat and they are not easy to find
other cards like the 580/570 are barely matching a 1060 in performance..

Bobby made the right call in my view(From someone who builds GPU workstations for living)

[Muhammed_Hamed]

idnok Agreed!
on a single 1080Ti I can fit up to 60 million polygons, I never ran out of VRAM on what I do, and considering how memory effecient Vray GPU has been, the 1080tis are still really good value

Thank you for this!
I wish i had this few months ago instead of writing my own and annoying ChaosGroup guys for hours.

[piotrus3333]

Bobby mentioned 20GB of RAM (not vram). I was referring to that.
win10 on a work machine right now takes only 470MB of vram (gpu-z)
5GB of vram for 3dsMax scene is not an exageration. and its not polys - mostly textures. anyway - this can easily be checked even in win10 task menager.

I bet that your 3dsMax needs at least 5GB of video ram to display your scenes. that leaves just 6 for rendering on 1080Ti.

I actually had a second card just for my mammoth 43" 4k monitor, but I removed it and to tell you the truth, I don't remember why. Now, with the two 1080ti's, I don't have any more power connectors.

[glorybound]

Would this work for my monitor? It doesn't seem to need any extra power to it. I have a 43" 4k LG.

[piotrus3333]

can you check how much vram does your usual scene takes (just opened in 3ds max)?
task menager > performance tab > gpu

[glorybound]

I saw a guy render a 1:30 second animation using Unreal and all in 20 minutes. How much time do you think it would take someone to bring a V-Ray scene into Unreal and pull this off. I mean, everyone's jaws dropped, however, he didn't say how much time it took to get his model into Unreal.

[glorybound]

Will this guy power my 43" 4K monitor in 3DS MAX? No external power and one slot.

I have a large exterior with everything in it. My shared GPU is 64GB and my dedicated is 11GB. I have no clue what the difference is. This isn't the kind of scene I would use GPU on, unless I could. When I open my typical interior I'll see what that read.
