32gb ddr4 or 64gb ddr3?

[gaudintig]

Hello my question is about game performances and computer configuration.
I have now 32gb of ddr4 ram on my pc, although it is way enough for casual gaming as you know it can be sometimes insufficient when it comes to cities skylines and using lots of mods and assets.
So I’m thinking of extending my ram to 64gb. Problem is: I have 4x8gb ram configuration and the 4 slots on my motherboard are used. So I have no choice to buy 4 new rams of 16gb. And I am unfortunately not a millionaire, so I was thinking about taking ddr3 ram because it is way cheaper, but it is a smart choice in your opinion? Will I have better performances for cities skylines with 64gb of ddr3 ram rather than 32gb in ddr4? (also considering that the ram I have now is 3200mhz witch seems pretty high grade).
Sorry for the long message and my struggle with English I hope you’ll understand my question.
Thanks in advance.

Is 64 Gb of RAM really even nesessary unless you have some kind of industrial workload?

Necessary? No. But if you use workshop, then you could use up more than 64GB of RAM. I loaded someone's city of over 4,000 workshop items and it reached over 50GB. But 90% of it was unused in the game. It was just basically acting as a RAMdisk to hold info in case it needed it. Otherwise, the game was only using a few hundred assets in the game.

But in my game, cities.exe uses 2.5GB of RAM @ 1080p resolution (1920 x 1080), while my main rig uses 4.5GB @ 4k resolution (3840 x 2160). I use no workshop.

Out of curiosity I once enabled every asset I had to see how much of my 32GB it would use...

On an average city build though, I use only around 1500 assets and so most of these are disabled and I still have ample RAM available. Unless you're the sort of builder that requires tons and tons of assets and props for intense detailing, then 32GB should be more than adequate and 64GB would be overkill imo.
The only thing that would tempt me to upgrade from 32GB to 64 would not be for gaming purposes but rather as scratch memory space for 3D artwork and rendering.
