GDS

yes I agree about separate all OS and ProxMox How much space would you recommend for Proxmox? website says 1 Gb mini, and you have 256Gb (if I remember) concerning a SSD or an USB flash drive I don't see any huge differences (the last one can have 440/330 in read and write and there fits perfectly on the back of the computer) 😉 So i will go through a speedy USB key

you are DEFINITELY right it is a Gigabyte AORUS MASTER I am soooo used to have ASUS for Hackintosh that I wrote ASUS and not GIGA 😄

Thx a lot So i am studying your flow to have everything fine About ASUS, GIGABYTE, I don't think it will make crazy troubles, let see how it goes but I am pretty confident concerning the compatibility I will go through CLOVER that I know well and I love, OpenCore looks super nice but i guess too early for me to use it and with CLOVER I can overclock the Radeon VII (Power Table Generator injected in Clover) to have a beast on water 😄 About dual GPU yes tricky tricky but I love challenge and I guess it can help the community: I thought to approach the problem in clean way, I mean I need the 1080Ti only for Win10 and the radeon VII only for Catalina I can of course put flags in CLOVER to not activate the Nvidia so no conflicts as CATALINA will consider the 1080Ti not existing at all and having on WIN10: 1080Ti and Radeon in Windows 10 but this solution will be a huge source of conflicts for sure soon or later but I thought to use PROXMOX for each VM: activate the PCI of the radeon VII for the CATALINA VM activate the PCI of the 1080Ti for the Win 10 VM I guess it is the cleanest way, what do you think? I have a tiny question: i am not a Linux expert at all, and I ask to myself which hardware configuration (passthrough) could be the best: I have 2 NVMe, one would be dedicated to CATALINA and the other to WIN10 but about PROXMOX? is it possible and reliable to install everything on a 32Gb USB3 key and leave it as it or better to buy a new NVMe of 128Gb dedicated to PROXMOX (I dont think that divide one of the 2 NVMe for PROXMOX is good idea 😞 anyway it is very exciting to see how my rig will work and share with the community how it goes

Hello All, Just going to say thank you to @fabiosun to this guide, and all of the people who participate on this discussion and have same rig as me a huge step forward to OS X lovers and Threadripper users (btw fabiosun, we had long discussions by PM, years ago on another forum about OS X, I was using a 2699v4 with 2 Titans X, don't know if you remember) 😉 About my rig used for this project: a 3970X + GigaByte TRX40 Aorus Master RADEON VII + 1080Ti Extreme 128Gb DDR4 2400 2x m2 NVMe + 2x SSD + 6 x 10Tb HDD EVERYTHING will be fully water-cooled in EKWB (thermal dissipation more than 1500W) and OC to have the best of each part! Again thx to all and I will post my different steps and results concerning the programs I use: 3D modeling, VR, AR, XR: Blender, Unity, 3DCoat, Reality Capture, ... But also others like: DaVinci, Adobe suite etc etc
