Here's how much RAM your PC needs to run smoothly

Is there a case for more than 8GB of RAM? Sure there is, but the bang for the buck trails off beyond that point.

1GB
1GB of RAM is the minimum system requirement for the 32-bit version of Windows 10, and while I've got Windows 10 to run on this much RAM, I really don't recommend it.
1GB of RAM is just enough for basic operations like web browsing (although don't expect to run a browser with dozens of tabs open), email, word processing, and light image editing.
Any sort of gaming is going to be painful with this little RAM, and carrying out tasks such as photo processing or ripping a CD will pretty much take over the entire system. As for video editing, forget about it.
I'm not making a strong case for 1GB of RAM simply because I don't recommend going this low. No matter who you are or what you do with your computer, you could benefit from more RAM.
2GB
2GB of RAM is the minimum system requirement for the 64-bit version of Windows 10. You might get away with less, but the chances are that it's going to make you yelling a lot of bad words at your system!
With 2GB you should be able to do pretty much everything with your computer that a computer is capable of doing, such as gaming, image and video editing, running suites like Microsoft Office, and having a dozen or so browser tabs open all become possible. Sure, the shortage of RAM is going to be a bottleneck on your system, but 2GB is enough to get some real work done.

4GB
If you're running a 32-bit operating system then with 4GB of RAM installed you'll only be able to access around 3.2GB (this is because of memory addressing limitations). However, with a 64-bit operating system then you'll have full access to the whole 4GB.
The difference in performance between a system with 2GB of RAM and one with 4GB is like night and day. Even on a 32-bit system that limits the RAM to a little over 3GB, the performance boost is well worth the cost. Not only do applications run faster, but you can also run more applications simultaneously, which comes in very handy if you run suites like Microsoft Office or Adobe Creative Cloud (say you want to run Microsoft Word and Excel, or Adobe Photoshop and Lightroom).
If you have a 64-bit operating system, then bumping the RAM up to 4GB is a no-brainer.
All but the cheapest and most basic of Windows 10 systems will come with 4GB of RAM, while 4GB is the minimum you'll find in any modern Mac system.
All 32-bit versions of Windows 10 have a 4GB RAM limit.
8GB
Note: You will need a 64-bit operating system to make use of this amount of RAM.
Now we're into performance territory. If you're serious about your PC, then I consider this to be the new default. If you're buying or building a machine dedicated to photo or HD video editing and rendering, or just want a fast system, then 8GB of RAM really is the minimum you should consider to avoid frustration.
This is the amount of RAM recommended by Adobe for users running Creative Cloud applications.
8GB of RAM is not expensive. Sure, get the OEM to fit it into a new system and you're likely paying a premium (especially if that OEM is Apple), but from an aftermarket supplier this can be had for under $40.
16GB
Note: You will need a 64-bit operating system to make use of this amount of RAM.
Is there a case for more than 8GB of RAM? Sure there is, but the bang for the buck trails off.
The time when more than 8GB of RAM becomes useful and starts paying for itself is when you're running a number of resource-heavy applications simultaneously especially image or video processing (even 4K video), CAD, or 3D modelling. Try running Premiere Pro, Photoshop, and After Effects side-by-side on a system with 8GB of RAM, then bump that up and feel the difference.
Having more than 8GB also comes in handy if you make extensive use of virtualization tools such as Microsoft Hyper-V or VMware Workstation, especially if you run multiple virtual machines simultaneously.
16GB+
Note: You will need a 64-bit operating system to make use of this amount of RAM.
You're now deep in the realm of heavy lifting. A workstation with more than 16GB of RAM will be a do-anything system. This is the sort of system that will be able to run multiple resource-heavy applications or virtual machines simultaneously.
Remember that 64-bit Windows 10 Pro, Enterprise, and Education will support up to 2TB of RAM, while the 64-bit version of Windows 10 Home is limited to only 128GB.
