Depends on your use cases, 8 is just barely enough to scrape by using about 3-5 chrome tabs and a game at the same time or running a game and streaming at the same time. 8 is the lowest limit that you could safely go in my opinion for multitasking on windows 10. 16 is pretty much the middle ground standard for PCs and you can run as much in the background as you want really with little to no worry’s unless you know a game takes ram, or if something you are doing requires a specific amount of allocated ram I would recommend 16 just for that little extra security and piece of mind knowing you won’t run out of memory easily.
