should i upgrade to 32gb ram (ddr4)?

it always depends what you are going to do with it... me personal wouldnt spend money for this upgrade

From what I've heard anything other than rendering it won't be worth it. You get bragging rights though

unless you are doing video/photo editing then it's not worth it

Not really, unless you are need to upgrade so just upgrade it tho

Not really, I you aren't using applications that will use the whole RAM. Otherwhise you will pay for RAM and it will do nothing.

This may be an unpopular opinion, but in my opinion yes - it is worth it.
I live with 16gb as well, but it's lacking sometimes and if I didn't have other priorities I'd definitely upgrade to more

16gb is fine for gaming. only upgrade if you render something or edit videos

Definitely upgrade, When i upgraded my pc ran stuff alot better

So it depends on what you do. If you say this amount of ram is not enough for me, upgrade it.

it's totally worth upgrading if financial is not a problem, you can do things easier and faster
