I think it's pretty clear what it is and any comments I have about it are not important and people can make their own minds up about it after reading the review.

I'm hoping they do that soon too and to see how they both scale. Would be nice to see, but I don't think their will be much in it if anything.
Is your boot drive set to GPT not MBR and are you turning off CSM and using UEFI too boot in the motherboard bios too ? You can only use UEFI to boot of windows if set to GPT or the pc will not boot. You can't use ReBar without UEFI.
There is no ReBar VBIOS for your card yet, the latest vbios they have listed is not the ReBar VBIOS for you MSI 3080 Trio.

You need to read this for your card :-

Important part for you is this part at the bottom of the link above, it says you need to update with dragon centre or the msi liveupdate :-

Make sure to have .net framework 4.0 installed too and turn off any antivirus the period it's searching for new updates. Could be your virus checker refusing to do it, other people had virus protection cause issues too.
.net framework 4.0 download page :-

good stuff , enjoy 
.Well now you know how to make it work you can now help all with the MSI cards that have the same problem
.Have you disabled CSM and using UEFI ? but you need to make sure your windows install is in GPT not MBR and if in MBR you need to convert it to GPT with the windows tool or you will not be able to boot windows without CSM if in MBR.
Also make sure all virus protection is off when running the VBIOS tool update as that is known to stop it working right too. So you may think you flashed it and got a reply of all ok but reality is the windows virus protection or other protection deletes the file in the background or stops it running right.
Only things you need to have enabled in the motherboard bios is Rebar and 4G decoding and UEFI and csm disabled.
In windows you need to have the latest nvidia drivers installed too, when flashing the gpu and when enabling it in the motherboard bios.
