Gaming rigs are only really capable if you do single small items. If you do assemblies they're a waste of time. It's not so much the CPU that is the issue. It's more the GPU. A strong graphics chip is essential.
Mine is a few years old fitted with a 4gb nvidia 1050ti GFX chip and it has its slow down/crash moments. When it comes to any simulation of a toolpath it has a nightmare.
The i7 cpu itself is barely worked.
