Should I get myself a new PC if I can only watch youtube on 480p on my 11 year old notebook and work on the office where it is slow and something is lying and gambling is not possible any more?
That would be the question how "is it worthwhile to buy a new car if the old one no longer has TÜV and half falls apart?".
The answer is: Yes, if you need a car, a new one would make sense.
For what you do, it does not have to be the best of the best. Pick a nice notebook and good.
In your question, you answer them yourself. Buy new… After 11 years. Since a Aufrüstpotential is no longer meaningful implement.
