32 GB of RAM is excessive for some people, but for others it may be needed if you do a lot of resource intensive tasks or heavy video editing, but for most most people 16 GB to 32 GB of RAM is often enough.
32 GB of RAM is better than 16 GB of RAM as having 32GB of RAM will make your computer run much faster and much smoother than 16 GB of RAM, especially if you do a lot of tasks that require a lot of power such as 3D rendering, heavy video editing, play games that use a lot of resources etc.
Although 16 GB of RAM can be sufficient for many users, but it doesn't hurt to have more RAM than you think you'll need.
You can tell if you need more RAM by the way your computer is acting.
If your computer frequently freezes, lags or is slow or crashes, or the browser crashes or applications you use crash, or your RAM usage is consistently at or near 100 percent in the Task manager then it's a sign that you need more RAM.
Other signs that your computer needs more RAM are slow application loading times, sluggish performance, especially when switching between tasks, slow response times etc.
Having at least 8 GB of RAM is recommended, although 16 GB to 32 GB of RAM is best for most people.
If you're a gamer or video editor then 16 GB of RAM can also be sufficient, but if you do other heavy use tasks or do heavier gaming or 3D rendering then you may need 32 GB to 64 GB of RAM.
64 GB of RAM is overkill for most people and the average user and most gaming.
16 GB of RAM is most often enough RAM for the average user, but 32 GB of RAM is ideal for gaming, video editing, multitasking etc.
Although if you do, do a lot of video editing or 3D rendering, running multiple virtual machines or do any specific high end simulations then 64GB would be needed and be a good idea to have that much RAM.
People that need 64 GB of RAM are video editors, graphic designers that use memory intensive applications like Adobe Photoshop, 3D artists, After Effects or Premiere Pro.
Or if you're a software developer who frequently uses multiple virtual machines for testing or development.
Or if you use some demanding simulations, like flight simulators, for example Microsoft Flight Simulator or if you use your computer for scientific research then you may require 64 GB of RAM or sometimes more.
Although the average user does not need 64 GB of RAM, such as for basic tasks like email, web browsing, watching YouTube, streaming, office applications etc.
And most gamers don't need 64 GB of RAM, although 32 GB of RAM is recommended for the latest AAA games, but 64 GB of RAM dose not provide any significant performance improvements for most gaming scenarios.
And if you only use your computer for tasks like light photo editing, casual gaming, streaming, light video editing, etc then 64 GB of RAM would be overkill.
Although it doesn't hurt to have more RAM than you think you'll need.
But for most people 16 GB to 32 GB of RAM is enough.
