Specs of the new PC?
If it's Ryzen non-X3D, you won't be missing out on much. With Win10, you will actually be saved from the carpet being pulled from right under you where entire features get changed without notice.
Two examples (very annoying for me)
It used to be that you opened a file in Notepad, pressed CTRL+P and then Enter and the file would go to the default printer. In Windows 11 after some update, pressing Enter now opens up the Printers list. I have to manually point the mouse button on the Print button to print! I'm sure there is a shortcut for that but why the hell did they change it without any sort of notice? A little message saying "This is what we changed. This is how things will work now" would have been very appreciated.
Dragging a text file on Notepad would open the file. In Windows 11, they introduced multi tabbed Notepad with some update and now a new tab opens for every dragged file. AGAIN, they did this without any notice, did not inform existing users how the change would impact them and did not inform them how to revert to the previous behavior. EXASPERATING, to say the least.
In short, if you have vanilla Ryzen 5000 or 7000, stick with Windows 10 for the time being.
