Nice to hear you went with Ati again
Keep us posted on your thoughts on the card when it has some mileage!
As Requested here are my thoughts and experiences after the first ~10 Days with my RX Vega 64.
As someone who owns a High-End Card for the first time I'm both really surprised and a bit disappointed by the build quality of this thing. As mentioned above I got myself the ROG Strix variant from Asus with a massive 3-Fan cooler that keeps the card quiet. So far I didn' t feel the need to undervolt it. The metal backplate looks great, but I'm a bit disappointed that the shroud around the fans is plastic, my previous Zotac GTX 970 had a metal shroud, it just felt more premium despite being a Mainstream card.
That being said the massive size is just a bit too much for current case (a Lian Li HTPC case), but then again I was never a big fan of my current case to begin with, it is way too restrictive for Air Flow, with the 970 I was at least able to Frankenstein a 120mm fan into the case to force air out of the CPU area through the HDD Caddy, with the much longer Vega Card this isn't possible anymore. This is now the perfect excuse to get myself a new case and an AIO Watercooler for my CPU in the near Future.
On the Software side I now settled to go with Manjaro Linux (Arch Based Distro) and the OS / Mesa Driver.
I started out on Ubuntu 18.04, but I guess I did something wrong while Purging the Nvidia Driver and the Moment I tried to Install the AMDGPU-Pro Driver the System was borked to the point that it wouldn't boot anymore.
I then played around with Pop!_OS 18.04 and 18.10. BTW, Pop!_OS is a great Ubuntu Variant for anyone that is looking for a Distro that comes with very little preinstalled Software. Since I first intended to use the proprietary Driver I opted for 18.04 since it allowed me to use AMDGPU-Pro. Performance with this Driver is great, but both Fullscreen Videos and games Tear like crazy with this Driver, even if you enable VSync in Game. I then played around a bit with 18.10 and the Mesa Driver, this Combo had pretty much the same Performance with the benefit of the Tearing being eliminated (I never seriously Benchmarked this, but Rise of the Tomb Raider in 4K Maxed out landed at around 45 FPS Average with both Combinations). Everything seemed fine until I had a Power Blackout while the System was running. For some Reason I could now only boot into the oldkernel Option of Pop!_OS, and that was harmful to my Performance.
I then opted to go with Manjaro since it uses a Rolling Release cycle which means that they implement new Kernel Versions and Features much faster than Ubuntu based Distros do, plus it makes it super easy to switch between Kernels in case a older one works better.
As for Performance: I'm super Happy with my choice. It won't push all games to 4K 60 FPS with everything maxed out, but the recently Ported DiRT 4 runs with the High Preset plus Advanced Ambient Occlusion and Screen Space Reflections enabled at a locked 60FPS in 2160p, Hitman maxed out, same resolution doesn't dip below 30, it feels like 40-50 most of the time, Doom 2016 with Ultra + Nightmare Settings enabled just misses out on being a locked 60FPS, and this one is being played through Proton mind you, so there is some Performance loss for the Translation layer. Hellblade, again maxed out and through Proton (Not officially Whitelisted) never goes below 30, but In have to say that it doesn't feel too great as the audio can easily go out of sync when there is some Shader chaching going on.
Overall I can highly recommend this Card for High Resolution gaming on Linux, especially with the Open Source Drivers,
