    I am thinking about doing a build with an i9 7920X --- I assume that the CPU_ID in the config.plist will need to change? Anything else?

    You don't need any CPU_ID for any of the X299 CPUs. Some users are putting one in for cosmetic reasons but I found it can hurt the hack.
    And nothing else will need changing :)

    I have a major question: Does video acceleration with Vega work properly? Does the UI feel in every case smooth, for example if you you open Mission Control while having many apps on your screen?

    Background: I noticed a really big difference between iGPU enabled (and active) and disabled - even if you have a dedicated GPU. When disabled, the whole UI feels laggy and underperforming - even on my GTX 1060. Going back to my GTX 780 (with iGPU active and no web drivers) made the UI responsive - at any given time.

    So in essence, macOS seems to do _something_ at any given time with the iGPU, even if a dedicated GPU is installed. But Skylake-X does not have one so my question is if macOS HS and Vega play as nicely together as with the "normal" CPUs with iGPU. I would like to build a X299 setup with Vega as well but I would like to be sure that the UI feels like it should - before I spend a couple of thousand bucks.

    Vega does not provide video acceleration properly. i think we having all these issues since its not fully supported yet since the imac pro hasn't been released yet. any program that stresses the gpu for acceleration like fcpx seems to have issues. other than that in general desktop operation and it seems to be stable. The drivers need to mature before vega compute cores are used.

    regarding the x299 setup, i think its better to wait for the imac pro to be released since the drivers and 10.13 will mature. its better to wait and let the software fully support the chipset before spending on this expensive platform. The decision is your whether you want to be the BETA tester at the cost of acquiring cutting edge technology.

    The vega acceleration is about as good as the nano/ fury. But, as per the previous post, it has it's problems. Hardware acceleration is broken in some software (Chrome eg) and now and then I get a GPU freeze. It's still fine for my graphics work.

    The X299 is good. Better than any other I've tried and I wouldn't hesitate to get it again. There are still issues with wifi and bluetooth, but I'm sure kexts will come for those at some point.

    All up though, mainly because the vega and the platform are now natively supported and any hack is going to be, well, a hack, there seem to be less issues or barriers to a stable work machine than most other systems.

    @pete1959 I just ordered the following:
    i9 7920x
    Gigabyte Aorus x299 Gaming 7
    32gb G.Skill RGB Series 3200
    512gb M.2 WD Black SSD
    In Win 303
    1000W Roswill PSU
    EKWB L360 Liquid Cooling

    I will be using my old:
    Nvidia GeForce 750 Ti
    GC-Alpine Ridge Thunderbolt 3 adapter

    1. I am assuming everything is within standards.
    2. What can I do to prepare for install?
    Any and all suggestions are more than welcome.
    Thank you

    If I want to clock this beast at 4ghz base speed. Will macOS automatically adjust or will I have to modify the SSDT file?

    I'm running my 7900 at 4.8 and no modifications to SSDT required. In fact I just have the clover generated SSDT and no modifications for anything. Seems fine.

    Do you think Sierra would run on your build?
