A project like yours would take a few hours at most on modern hardware. CPU speed is extremely important here, followed by GPU and RAM speed. RAM quantity matters but doesn't affect speed much. More RAM allows you to create large projects.
Metashape automatically uses your hardware "to the fullest" - if it's not, then there is a bottleneck somewhere. A common bottleneck is your storage device. Use an SSD, not a hard drive, to store your project images. Otherwise, the hard drive is likely to be a bottleneck. You can check this in Task Manager - if the drive with your images is at 100% usage, then it's a bottleneck
If you're talking about upgrading your existing components, it's probably better to build a completely new PC. You should get the CPU with the fastest clock speed that you can afford. A 13900KS would be at the top of my list for a new PC, but that's $700 for the CPU alone. So instead you might want to look at an older CPU like a 10900K that can run at or above 5 GHz (that's what I have). You would need a powerful water cooler to achieve 5+ GHz full-time, but it blazes through photogrammetry projects like nobody's business. It's a lot faster than a 4.5 GHz Xeon with 48 threads, even though it only has 20 threads.
If you are not ready to upgrade, you should overclock your existing CPU as much as possible. That will help speed up your processing and might only cost as much as a good air cooler or AIO water cooling loop.
The GTX 1070 is OK for making depth maps but it has little to no impact on creating a dense cloud since that happens on the CPU.
Lastly, do you really need the point cloud in the first place? You should try making your mesh using depth maps only and see if the results are satisfactory. That's a much faster process to begin with and would take a lot less time to create a mesh.
