Optimal computer configuration?

Hello everyone ! :smiley:

I need some advice to renew my computer park, I mainly use Nuendo & Cubase for music production, creation and post-production and a lot of plug-in and virtual instruments

I am renewing my computer and I would like the configuration to be the most compatible, stable and optimal knowing that my sound card is a RME UFX 2

:arrow_right: > Overall, I intend to take the latest generation hardware, it’s a first idea but here is the configuration I have planned:

:arrow_right: Motherboard:

:arrow_right: Processor :
Intel Core i9-9900K
INTEL i7-9700K

:arrow_right: Graphic card :
Asus DUAL-GTX1060-O6G

:arrow_right: Memory:
Corsair Vengeance LPX 64GB (4x16GB)

:arrow_right: Disk ssd M.2:
CORSAIR Force MP510 1920 GB

:arrow_right: System:
Windows 10 home

:question: My main questions and doubts:

Which processor to choose, Intel i9 or intel i7?
It was also said that the i5 was very good and suitable for audio, but I will also have to perform video tasks after effect & premiere

A technician advised me pentium, in general, because it is simply what is more widespread, but especially that all components (motherboard, processor, graphics card) are "pentium "for the best possible compatibility, do you have other elements to give me?

Windows 10 home? I was told it would be best?

Is there a problem in selecting the material I chose?

Thank you all for your time, and look forward to hearing from you if you can help me !! :unamused:
