iMac Pro + eGPU, any suggestions?

Hey gang- long time lurker, first time poster. I just purchased an iMac Pro to use as my main workstation. I'm a motion graphic and 3d artist and would like to purchase an eGPU to run 3rd party renderers that require Nvidia cards. I've dug in, reviewed the guides and builds, and noticed that many pros I followed for guidance use the 1080 ti. From my searching it seems like this card has been replaced, is its successor the 2080 ti? There are only two builds in the guide, both using 1080ti's, and from my research it seems like the 2080 ti would be worthwhile but the different versions, Black, XC, XC2 start to make my head spin. I haven't built a computer before and am somewhat out of my element with the deep-in-the-weeds technical specs.

I'm wondering if anyone could provide some guidance on a solid card to pick up in lieu of the 1080 ti (or a good source for where to purchase non-used or refurb) and a housing to fit. I apologize if some of this is fully fleshed out and documented in the extensive info on this site, but frankly there's a point where some human interaction is appreciated, even just for confirming what I'm seeing.

Many thanks in advance for any suggestions, info, or guidance!

iMac Pro 10.13.6 / Sonnet 550 / NVIDIA GeForce GTX 1080 Ti

RTX cards (2060, 2070, 2080, etc) don't work in macOS. Pascal or older cards 1060, 1070, 1080 are supported only up to High Sierra (not macOS Mojave).

The cards should work in Windows though. Search https://egpu.io/builds/ for
Brand: Apple
dGPU: AMD
OS: Win
eGPU: Nvidia

Mac mini (2018), Mac Pro (Early 2008), MacBook Pro (Retina, 15-inch, Mid 2015), GA-Z170X-Gaming 7, Sapphire Pulse Radeon RX 580 8GB GDDR5, Sonnet Echo Express III-D, Trebleet Thunderbolt 3 to NVMe M.2 case

Pretty much, if you want to use Nvidia, best to work in bootcamp, because MacOS isn’t going to use them. If you want to work in Mac OS, consider getting an AMD card.

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

find a used 1080 ti  ... buy from a reputable ebay seller and add a warranty if you are concerned. Stick with 10.13 though or you will not be able to use the nvidia card.

Thanks for the guidance all, much appreciated.

I ended up finding a used 1080 ti on FB marketplace and will be pairing w Sonnet 550. Attempting to get it up and rolling in the coming days, will report back- thanks again!

please keep us updated ... there are some threads already here for some third party renderers and from what I gather some work better than others over eGPU.

Hey gang,

I'm back with an update and looking for some guidance. I feel like I'm so close, but can't quite get there. From other threads I've gathered that a system info or dump can be super helpful to those trying to assist and troubleshoot but I'm honestly not sure how to get my system to spit that info out- please let me know and I'll be happy to post asap. Through a combination of those two scripts, various patches, and referencing other posts, I feel that I'm close- the system is at least aware that an NVIDIA chip is connected (I think)- but I cannot get over the hump to full functionality! Any help and guidance is appreciated, thank you so much in advance and let me know if there's any further info I can provide!

Tried:
- Referenced build guide and mirrored processes for both the two iMac Pro builds as well as iMac 5k
- Includes installing web-drivers with SIP enabled
- Installing CUDA elements from https://developer.nvidia.com/cuda-downloads?target_os=MacOSX&target_arch=x86_64&target_version=1013&target_type=dmgnetwork
- Ran both- automate-eGPU-EFI - and - purge-wrangler.sh

Currently:
- Start up with eGPU unplugged, plug in at log-in screen, log-in, and Sonnet lights up as well as EVGA colors on 1080 ti
- System report shows 'NVIDIA Chip Model' under Graphics/Displays but does not identify specifics of card
- No device found in the ECC of Driver Manager

OSX 10.13.6
CUDA Driver Version: 418.243
GPU Driver Version: 387.10.10.10.40.130
NVIDIA Web Driver: 387.10.10.10.40.130

I thought SIP was supposed to be disabled(?) ... maybe things have changed since I did mine. Also, I have my eGPU powered on but I wait to plug in TB3 cable until after I am logged in. You are indeed so close... maybe a driver issue(?) Update your signature so people can get up to speed faster with your build details. I can't add anything relevant so I'm rambling...

@esatamacmodular Thanks for the reply and the tip on the signature, I just updated. And the steps from the build and post associated w https://egpu.io/forums/builds/2017-27-imac-gtx-1080ti32gbps-tb3-mantiz-venus-macos-10-13-3-build-for-octane-render/ suggested installing the web-drivers with SIP enabled, then turning it off and installing the nvidia-egpu-v6.zip. both steps I completed but am still having issues.

I will try your  suggestion of plugging in after logged in and see if that helps. This might sound super n00bie, but how will I know once it's fully functioning? I assume I'll see the card in the ECC slot, but beyond that? Thanks again for your help- and to anyone else who can lend guidance!

Mixing solutions is never a good idea and makes debugging almost impossible. Please start over fresh and use either automate-eGPU EFI or purge-wrangler (not both). The former requires manually installing NVIDIA Web Drivers first. Once you attempt one of these solutions, post screenshots of System Information > Graphics/Displays instead of trying to mix solutions. Do not reference guides older than macOS 10.13.4. The setup for them is different. Always check for matching system configuration (especially OS and discrete GPU) before following a build.
