I have been saving for a long time to upgrade my build, and I want to go big, and I mean BIG. Currently I have most of the main components of my new build picked out. But I cant decide on the GPU. Im hoping for some input from experts.

I am a indie game developer and gamer, I do heavy 4k animation and high poly 3D modeling and rendering. I also game alot. I am building a i9-7900x, 128gb ram, 3 ssd/2 hdd, custom liquid cooled system and i plan on liquid cooling cpu and gpu. My issue is what GPU to use.

I am considering a quad Titan sli or a dual gtx 1080Ti sli but im not sure which i should choose. First im not even sure if the motherboard i chose (Asus ROG RAMPAGE VI EXTREME) supports quad sli titans that are custom liquid cooled (if there is enough room to fit them all). My question is, with what i am using the pc for, both gaming and lots of heavy rendering and designing, which GPU's work more in my favor for a good balance of gaming performance and editing power?

As others have mentioned, the new Nvidia GPUs are going to be announced tomorrow. As for the rest of your build, I'm not sure that the LGA2066 socket is the right move for your build. Most professionals that I know who do 3D modeling, use relatively low core Xeon or LGA 1151 (300 series) processors along with 2-4 GPUs per rig. I'm not an artist, but I believe the CPUs are used mainly for the viewport, and the GPUs do the heavy lifting. If they go beyond 4 GPUs, then they use netrender or some other program to run a single render/export through GPUs in more than one rig. Please invest in a top quality power supply of sufficient wattage.

As for liquid cooling, I recommend skipping the custom loop. Simply buy the EVGA GTX 2080 Ti...

SLI support is fading fast, and, only dual GPU SLI works now, with triple and quad SLI long since defunct for gaming (triple/quad killled off 2 or 3 years ago, or so I had heard....)

the 7900X is a beast, but, it is rather a hard sell over a 2950X...; especially with the latter having more RAM support, ECC RAM at that, and many more PCI-e lanes available...useful if pondering 4 GPUs for whatever functions...

As for liquid cooling, I recommend skipping the custom loop. Simply buy the EVGA GTX 2080 Ti hybrid GPUs and get a closed loop for the CPU, so that you have practically zero maintenance. As for gaming vs rendering, just dedicate "one" GPU to gaming, and then use all GPUs for rendering/exporting.

I also recommend posting your question to fellow artists/animators who have similar rigs in their homes. A lot depends on your budget, as well as which programs that you use; I'm sure there are many. I see many questions like yours over in the Blender.org forums.

That is very helpful information, I hadent considered a xeon cpu. My concern though is that xeon's arent good for gaming. But i was actually not aware the 2080's would be out soon. Ill have to keep that in mind. No sense in not just waiting. As for SLI, i could see the benefit from a render farm, but maybe in the sense of just a editing build, 1 titan for editing and 1 2080(Ti) for gaming would be the best outlet. Thanks for your help, and I will surely ask some other people with similar builds. And also thanks to @Popatim for mentioning the 2080Ti's
