decide to upgrade old pc

I have a old PC with this specs:
CPU: i7 2700k
SSD: Samsung EVO86
should i upgrade to newest cpu generations?

How can we know?

What do you do with it? What do you want to do with it?

For Cubase.

Ok, well we still have no idea what you’re going to use it for. 2 virtual instruments? 20? 40?

12 audio tracks only, no effect? With effects? 34 audio tracks? 48 audio tracks with a lot of plugins?

Orchestral library streaming?

Music to picture?

If it doesn’t do what you need it to do then upgrade. Mine did audio great but struggled with video which I had started to work with so I upgraded. I would not have bothered otherwise.
