How does one translate expressions like "PC Master Race" or "Ultrawide master race" into Chinese?
According to wikipedia :


  the term is used by PC enthusiasts both to describe themselves as a
  group, as well as their belief in the superiority of the PC platform
  in comparison to consoles, often citing features like more advanced
  graphics, smoother framerates, free online play, backwards
  compatibility, modifications, upgradability, customization, lower
  cost-over-time, open standards, multitasking, and performance.


Here I have to mention two words that is related to this term in Chinese culture:

鄙视链 a chain of contempt,

优越感 superiority.

Naturally, PC Master Race means PC优等民族, Glorious PC Gaming Master Race can be directly translated to 高贵的PC玩家, which is often seen among Chinese gamers, and is less "racism". To Ultrawide master race you can say 高贵的超宽屏用户
