10900k desktop CPU - 10 cores (20 processing threads) at 5.3GHz

16GB to 32GB is sufficient for most users.

For hard-core composers, the Platinum Laptop allows up to 128GB.

The Platinum Laptop uses a M.2 Ultra NVMe SSD for maximum performance.

On the PC, we now have complete "PCIe via Thunderbolt" support.

You must be running an up-to-date install of Win10 and have a motherboard that provides Thunderbolt-4 via USB-C port.

Antelope, RME, MOTU, Presonus, and UA have full "PCIe via Thunderbolt" drivers available.  

If the audio interface is Thunderbolt-2, you'll need a Thunderbolt-3 to Thunderbolt-2 adapter.  (Thunderbolt-4 can use the same adapter)

All major audio software/hardware is working well with Windows 10 x64.

Most major audio software/hardware is now working well with Windows 11.

"Pro" version has Group Policy Editor (easy to shut down OneDrive, Cortana, etc)... and can fully disable all automatic updates.

Safest route is to go with Win10 x64 (for now)... and upgrade (free) to Windows 11 in the future.
