New high-end computer... but now what?

Hi Sawyerpi,

Honestly, I think you're overthinking it a bit. That's a very solid parts list.

You don't need to connect the motherboard to the internet before installing the rest of the components. I'd assemble the system completely, update the BIOS if needed, then install Windows and drivers.

For Windows, I'd recommend creating a fresh installation USB rather than cloning an older installation from a previous PC. It tends to avoid weird driver and activation issues on a completely new platform.

As for the Ryzen and RTX 5090 concerns, most of what you're reading online comes from people troubleshooting edge cases. The vast majority of systems work perfectly fine. Just make sure the GPU power connector is fully seated and avoid putting excessive stress on the cable.

My suggestion: build it, update BIOS, install Windows, install chipset/GPU drivers, run some stress tests, and enjoy it. Those specs should handle just about anything you throw at them.

Good luck with the build!
