Nowadays even at 1080p 8GB of Vram doesn't cut it.

Software is a gas, it expands to use all available resources.

I have 32GB of RAM, and run out occasionally. At the moment I have two CAD programs, thousands of pages of datasheets and reference manuals, an IDE, and ~50 browser tabs open. I don't HAVE to have them all open at once, but it does save me a lot of time.

My next machine will have 128GB, and I expect that will run out of memory too.

Also, sometimes you need to use software that has a memory leak, so a bit of extra RAM gives you some more time before it crashes.

Photogrammetry can also get resource hungry.

Modern AAA games above 1440p and high settings usually can use that much VRAM.

8gb of ram is also not enough for anything particularly heavy.

Are you running ML models

Yes.

Satisfactory took 10gb for whatever reason. Playing 1440p at 90fps
