Well, of course, if you add a huge amount of stuff to the game it will take more resources. However, with Minetest RAM is not really an issue, unless you are keeping a huge number of chunks rendered (i.e. you have viewing range set to a high setting).
What Minetest really uses, is CPU. If you have a GPU (Graphics Card) on the other hand, Minetest will use that rather than hogging your CPU. I've found that with mods like Dream Builder, I can get a max of 20FPS on CPU, and 60CFPS when I have my GPU enabled.
So yes, Minetest will take extra resources, but not really RAM. If you are considering upgrading anything, either get a GPU or upgrade your CPU. The FPS I stated above when on CPU, was on my computer with an 8 core Intel Core i7 CPU @ 3.40GHz. With that in mind, what Minetest really needs for the client computer to run fast is a reasonably good GPU at its disposal. Personally, I have a GIGABYTE GeForce GTX 750Ti with 2GB of VRAM. It cost me $180 CDN (plus tax). I find it can hold up to 60FPS unless there are a ton of particles.
And, on the server side. The server will require more RAM mostly depending on the number of players. However, with extra mods, the server has to do a lot more work. However, like on the client, what really matters is the CPU. I ran a server on 3GB of RAM once with quite a few mods (one that introduced over 70 nodes), and Minetest never used more than 1GB of RAM even when I had 2-5 players on the server. However, the server did have a reasonable CPU.
Anyways, I hope the above answers your question.
