PC Performance Bottleneck with Bambu Studio and Mesh Operations

I use Bambu Studio to do a lot of mesh manipulations for custom prints (adding 3d text to objects mostly), and I want to build a new PC that will get better performance from the app. It's currently processing a boolean difference operation that takes several minutes, so I looked at the task manager in windows to see if I could find the limiting factor. Based on what I see, it seems to be memory bandwidth bound? Does that make sense to everyone else? I've got an AMD Ryzen 5 5900 chip with 64GB of RAM, sitting at about 15% CPU utilization during the operation. I noticed that it is doing a ton of memory transfers and using up to 8GB at a time for the studio process. I use very high resolution STL files, usually around 5-8 million triangles per mesh for my base objects.

When building a new PC to get better performance, what components should be my focus here?
