Its actually not "all good". There is something really weird going on since some months ago (some people traced it as far back as to around windows 1903 release) with DWM and Nvidia graphics cards.
I've come across two larger threads about it so far with little googling:
https://answers.microsoft.com/en-us/windows/forum/windows_10-performance/desktop-window-manager-dwmexe-using-high-usage-gpu/a14dae9b-8faf-4920-a237-75ebac8073f5 https://steamcommunity.com/discussions/forum/11/1643170269568692270/ .. and a ton more when you do a simple 'desktop window manager high gpu' search There are some different symptoms about it that people are describing, but basically it narrows down to DWM getting stuck doing something it shouldn't, and causing insanely high GPU usage when there should be next to no activity.
 
I'm also unfortunately sitting in the boat with this problem; Prior to playing any DirectX game I have no problems, but as soon as I fire up something (my test cases have been Monster Hunter World and Rimworld.. both performance extremes covered), my desktop becomes unresponsive thanks to DWM. Programs are still functioning, albeit they might as well be in a strangle hold given their performance.
When I exit the game, I'm left with flickering and unresponsive desktop, that only goes away after I log out and back in (or kill DWM, but that also breaks almost every other open program, so relogging is almost faster, and definitely simpler).
 
I'm nearing the point of completely reinstalling windows, but some posters had tried rolling back to previous windows and driver versions just to have the problem come back after a while, needless to say that makes me hesitate.

Stability is only a small part of it.
In fact, there is no real reason you could not just blindly pick up any other linux distribution and roll with it, if you only looked at stability. By far the biggest contributors are support channels and deployment/configuration tools that come with package, plus the availability of certification programs and free platform to demo and develop on.
 
RHEL(Red Hat Enterprise Linux) is so simple to roll out and manage on large, combined with very good training programs they offer - that hiring capable workforce to develop and support the platform is relatively cheap, as opposed to hiring very experienced linux developers to work on other platforms.
 
In the shadow of above, stability is secondary and will usually get considered afterward.
 
Smaller shops can roll with CentOS until they grow large enough to need RHAT support, at which point they can easily upgrade to RHEL licensing models and become entitled for it.
 
 
Main concern with IBM comes from their lack of innovation and toxic pro-profit business culture. If there is no profit to be had, it will get shaved.
This makes freely distributed tools exetras mentioned prime targets for such cuts, if the business cannot find way to make profit out of them - which they absolutely will try, because this transaction is massive enough to go down in history books.
 
There will not be any immediate impact, but this is at least as concerning as Article 13 in Europe, in the long term, and should be monitored with care.
(Maybe not entirely on that scale, because general consumer will never see the impact, but on enterprise space it is very considerable news)
 
Here is a news article that will hopefully make it a bit easier to understand the circumstances: https://gizmodo.com/what-will-become-of-linux-giant-red-hat-now-that-it-sol-1830074632/amp

I'm not happy at all about this acquisition. Having worked with and at IBM, this can be very bad for RHEL based products, like very widely adopted CentOS and Fedora. (IBM is extremely pro-profit enterprise, which leaves no room for private non-commercial products.)
 
Not to mention Ansible. Ansible has been a very promising and actually quite a bit used system automation and configuration tool in Linux enterprises. It would be a shame if it gets the blue hat treatment, i.e. slap a bill to every little version of it that is not AWX.
 
There is also negative impact for existing RHAT customers, thanks to new and renewed contracts, support and licensing models that IBM brings with it.
 
Commercial support.
Also RHCSA and other certifications provided by Red Hat. Basically they have official education channels to their product.
 

Being inspired by 7 Gamers 1 CPU and personal build 2015 videologs, I came up with an idea to try come up with a solution to allow me to put 2 things in to one box (plus some services) and then put away my standard desktop if all of that would magically work.
 
What I planned to put in the box:
1. Windows 10 gaming PC in Virtual Machine
2. Router and Firewall in Virtual Machine
3. Plex, Deluge and MySQL in Docker containers.
 
After investigating what would probably allow me to do this:
Chassis: Chenbro RM31408 - http://www.chenbro.com/en-global/products/RackmountChassis/3U_Chassis/RM31408 CPU: Intel® Xeon® Processor E5-2623 v3 - http://ark.intel.com/products/83354/Intel-Xeon-Processor-E5-2623-v3-10M-Cache-3_00-GHz Motherboard: Supermicro X10DAi - http://www.supermicro.com/products/motherboard/Xeon/C600/X10DAi.cfm RAM: Kingston KVR21R15S4K4/32  - http://www.kingston.com/us/memory/search/?partid=kvr21r15s4k4/32 Thunderbolt Card: DSL5320 - http://ark.intel.com/products/76719/Intel-DSL5320-Thunderbolt-2-Controller Sidenote: I chose dual socket motherboard for the possibility to expand for future needs.   Originally I was looking in to Asus Z10PE-D16 WS motherboard since they are my preferred manufacturer, but I came to realize after looking in to things further: Thunderbolt is not a simple plug-n-play PCI-E technology -> It would be flat out impossible to use Thunderbolt with this board, and given that there are no dual CPU socket motherboards with Thunderbolt available I had to go for the only alternative, Supermicro. Then after thinking about it a bit more.. Q: Is thunderbolt simply going to work over the PCI-E card and utilize GPU properly since it has to be implemented as separate module? I did see that it SHOULD work in the deployment video, but it was also Asus card and motherboard, so there was bound to be some compatibility.   AND not to keep things too simple: eGPU(?): Razer Core - http://www.razerzone.com/gaming-systems/razer-blade-stealth   Q: Is there any chance in a million years this would work, and passthrough correctly to the Windows 10 Virtual Machine or is it better to scratch the entire hope for eGPU possibility given the fact that I'm already planning such an extraordinary setup?   If this is something that would actually work, I will start the project and display the end results
