I have a PC that currently runs with 16GB of 2133MHz RAM, but I also have a 16GB set of 3200MHz RAM from Corsair Vengeance. I've read that when using both sets, the faster RAM will run at the speed of the slower one. I'm trying to figure out if it's more beneficial to stick with the 16GB at 3200MHz or if I should combine them for a total of 32GB at 2133MHz. My main use is gaming, with some other background applications running. Is the speed or the capacity more important for my setup?

I'd say unused RAM is pretty much pointless. If you're not pushing 16GB in your usage, just keep the fast RAM. Remember, faster RAM can improve performance slightly in certain situations, but if you aren’t maxing out your current RAM, there’s no need to switch.
It really depends on what you're using your PC for. If you regularly hit that 16GB limit in your tasks, then upgrading to 32GB makes sense. Otherwise, if gaming is your main focus and you don't often max out your current RAM, sticking with faster 16GB might be the better choice since you won’t see much performance difference with the slower RAM.
Yeah, I mostly game too and 16GB is usually enough. Just make sure to close background apps to free up resources. It helps a lot!
Look at your overall setup too. Sometimes the motherboard can limit your RAM speed, or if you switch to a single channel by removing a stick, it might slow down performance a lot. Check if your motherboard supports 3200MHz fully—if not, you might be better off sticking with the 16GB that runs faster.

Absolutely! I gave up on multitasking when gaming because it led to lag. Just focus on your game and keep it smooth.
