I'm planning to upgrade my CPU from an Intel 13600K to an AMD 9800X3D and have come across various opinions on whether I need to do a fresh Windows installation. I've heard that changing from Intel to AMD can sometimes lead to issues, but is a reinstall really necessary? What do you all think?

You really don't need to reinstall unless you start experiencing problems like freezing or BSODs. However, keep in mind that if you have an OEM Windows version, you might lose your license since it’s tied to your original hardware.
While Windows will technically work after swapping, it’s often smoother to do a fresh reinstall. It helps avoid any weird stability issues down the line, especially when switching between Intel and AMD.
I personally always do a fresh install when changing hardware. It just makes things easier in the long run, so I definitely advise considering it!
You don’t have to do a fresh install just because you're swapping CPUs. Windows has improved a lot in handling hardware changes over the years. That said, it can be a good idea to start fresh for a cleaner setup, so I’d recommend it, but it’s ultimately up to you!
In my experience, switching from a 13600K to a 7800X3D didn’t require a reinstall, and I haven’t had issues for nearly a year. Still, sometimes a fresh start is good to prevent future headaches.
