The CPU is not officially supported by Microsoft https://learn.microsoft.com/de-de...
Microsoft has drawn a hard line there. You just have to stick with Windows 10, which is still supported until at least the end of 2025.
Hi
Gaming, buy an i5... Enough. i7 you only need if you: Use programs that support more than 4 cores, e.g. in virtualisation, video editing, image editing etc.: Virtualisation, Video Editing, Image Editing etc.
Most games support between 1-2 or sometimes even 4 cores.
That's why it's better to get an i5 (my recommendation).
