Ideally you should have two sticks to take advantage of the dual channels on the motherboard. So even one more 16gb stick will result in a huge performance boost. Unless you're running 100 tabs in Firefox, 64gb is overkill.

Look at your memory usage to tell how much you need. Nobody here knows exactly how much memory your apps are using up. I would strongly advise you to stop opening up hundreds of tabs when you're playing computer games, though. You could probably run a very large number of tabs with 32GB RAM (some results say hundreds), but many computer games will want 16GB RAM for themselves.

Borderlands 4, for example, requires a minimum of 16GB RAM and recommends 32GB RAM. If you're going to run hundreds of tabs in Firefox at the same time, you'll need to budget for that on top of the game's requirements. On the other hand, if you're playing Dave the Diver, that requires a minimum of 8GB and recommends 16GB. Visual novels are closer to 4GB.

It's working this way. Even if you have enough free memory it wll load when you alt-tab from another program back to a game, (additional) micro stutterers are common in the first few seconds.

Firefox isn't preloading all tabs if that's what you assume. Thanks to an attentive forum user the Firefox add-on "auto tab discard" is now installed.

Last but not least if Firefox is clearly the cause of a stutter show of course it gets closed.

But some games keep showing a "slide show" or exhibiting micro freezings, despite high enough fps While 2x 16 GB will be "good enough" for most games I am asking if 2x 32 GB will be even better than "good enough?"

Check your RAM usage. See how full it is.

get 64 it's not that expensive, and you'll have a high ceiling of apps, browser tabs and games to use at a time,
but if you're just gaming and web surfing 32 should be enough, though at least be sure to buy ram with decent speeds and timings so you'll have less of those microfreezes in unreal engine.
