That is why I got a 3600 myself as I don't do anything that would benefit from more cores. Most 3900X cannot even keep up with my 3600 which runs all cores at 4.4GHz without a sweatBecause they’ve hit a brick wall in single core speed so the only way to make a ‘better’ cpu is to increase core count but what they don’t tell you is that a 3600x is as good as a 3950x 99% of the time barring of course niche applications, rendering h etc.
It is obviously nice to have more cores, but for normal use case there is little to no difference. I will only go core heavy once the 4000 series comes out as that will be the last gen cpu on AM4. That way I get better single core performance and have a cpu that will probably last a decade without a problem, assuming it won't get plagued with security issues. I mean if my 4 core Intel lasted over 6 years a 12 or 16 core 4000 series will probably last at least 10 years unless there is a major breakthrough where IPC goes up a lot.
