I'd look at resources when doing this in task manager and see where your bottleneck or system freeze up is happening, is it really the CPU, or RAM, or is the software your using having some sort of issue that it doesnt matter how much processing power you have backing it it could be a problematic program etc. From your description it seems like a shotgun approach to just replace the system, but i have done shotgun moves before and found out later that it could have been corrected differently.
If your CPU pegs to 90+% then I'd say you need a better CPU. If the RAM is all used up, which I find using up 32GB of RAM kind of hard to do, then you will know you need more RAM, if the CPU acts like its sitting idle and not an excessive amount of RAM in use when the system acts up then its likely a system corruption or software issue. Reinstalling the OS and software fresh might correct for this or the software itself has issues which the software manufacturer may be able to assist with correcting. Other cause other than software corruption or bugged software would be possibly a hard drive that isnt quite healthy as for a hard drive or SSD is critical to system health due to how the system uses virtual memory. A system that is moved around setup here and everywhere else might get bumped around when transported and hard drives dont hold up well to this.
