Yes.
I agree, and I often view computer costs in this perspective that you suggest.
BY THE WAY...I have used this site, or the original site that became this site, since about the year 2008, as I recall....
https://www.cpubenchmark.net/cpu_value_available.html
This site, in the past, has always provided me with the best up-to-date info on CPU speed vs price....
I really like this format, and anytime I needed a new CPU, I would always visit this site and make comparisons, before buying.
I will use this site to help me in my choice this time.
And so...I will just buy the i5 here:
Cheap..but...good enough...
And, I will use it until the day I die....
Maybe...
