I'm currently running a system with a 5070 GPU, a 14400f CPU, and 16GB of DDR4 RAM (2x8GB at 3200 CL22). While gaming on titles like Jedi Survivor and Hogwarts Legacy, I've noticed that neither my CPU nor GPU is being fully utilized, which makes me think I might be running into a RAM limitation.
I'm considering two options: upgrading to 32GB of DDR4 (16x2GB) which doesn't require any extra parts, or switching to 32GB of DDR5 (16x2GB), but that would need a motherboard replacement and the DDR5 prices are pretty steep.
I've checked out some benchmarks online, but I couldn't find tests that matched what I'm looking for, such as comparisons between 32GB DDR4 and 16GB DDR5 or different configurations.
Do you think the jump from 16GB DDR4 to 16GB DDR5 would significantly boost my FPS? If it's not a huge difference, I'd rather stick with DDR4.

It sounds like your RAM might not be the issue, especially since you're on a 100Hz monitor. If your CPU usage is around 70% and GPU at 60% while playing Hogwarts Legacy with mostly 14GB used, it could be more about the balance between your CPU and GPU rather than just RAM. I'd suggest monitoring the system performance more closely to pinpoint the bottleneck before making a switch.
I did some tests on my end, and I noticed that as long as you're tweaking settings for performance, the 16GB DDR4 should still handle most games quite well, especially if you’re not hitting 100% utilization on your components.
