Lol, some of us need the extra memory. I am going 96gb 2 dimms on my next build in a couple of months. I would go 128gb if I could get that on 2 ddr5 dimms.
I've been on 16GB DDR4 for years now.
Running an RTX 4090 too. Not sure if it's affecting me much. It probably is somewhat, I'd upgrade my CPU, RAM and MB but I'm trying to save money.
32GB for modern AAA games, 64GB for big games like Sims or modded games. Ram is system memory it's the fast low latency memory your CPU uses, the human equivalent is working memory where the CPU is the brain and ram is parts of the frontal lobe.
Consoles have merged system memory and the specific GPU memory know as VRAM into one pool called shared or unified memory. But this comes with many compromises such as forcing your CPU to use slow high latency GDDR memory (good for GPU very bad for CPU).
I've been on 32 GB since 2020 and frankly I'm not sure if I would even benefit to any degree of upgrading to 64.
Is there even anything out there that benefits meaningfully of having that much?
