Windows 10 Pro for Workstations

This one's quite suited for enterprise use like designing and rendering 3DCGIs for CADs, games, 3D animation and the list goes on as rendering a whole 3D animation stuff with so much professional detail is extremely time-consuming and it takes up so much computing resources. The same can go for rendering a video like for making movies and such but then, such kinds of intensive projects being done by the studios had been with the use of advanced computers and this edition is either unnecessary or optional enhancement.
Unless you're making something as intensive as the one stated above as an example, using this edition of Windows 10 for advanced gaming is a serious mockery among companies as it is extremely expensive. If you really want this edition that badly for your gaming computer, perhaps as an adult, you should plan things very carefully. If you're a pre-adult, it is way obvious that a standard computer should be enough.
A server-grade PC can act as a server or an advanced workstation but to find such a computer that advanced is going to be quite tough and you'll never find that kind of computer like that in the computer shops. Most of such computers are obviously for business use and the same can go for servers if you're going to buy one and besides, they're extremely expensive, even higher costs than the cost of gaming PCs you find in the shops.
This edition of Windows 10 has additional enhancements such as,

• Resilient File System
• Persistent Memory
• Faster File Sharing
• Expanded Hardware Support

This is quite useful for computers that use server-grade CPUs although you may end up using them as servers just because of those CPUs. In fact, there may as well be workstation edition of those CPUs so that they can fit those computers even better while keeping the client OS installed as intended.
The new edition of Windows 10 will be available as part of Fall Creators Update and what I previously knew about that update was that Powershell 2.0 would be obsolete in favor of newer version as well as SMB 1.0 which is what nobody should use for security safety.
