Not GP, but I have an i5 from around 2015. 4 cores, no hyper threading), 32GB ram. And it's still good enough for most things. Adding ram and a decent SDD gave it many extra years.
In the prosess of switching it out completely now though.
What kind of work do you do with those specs? I have a machine from around the same period with similar upgrades and I feel that it really is good enough, especially if you don't play video games.
It's actually the machine I use when working from home and it works fine.
PyCharm IDE on a moderately big project. We've recently focused on moving towards fully type hinted code base, using pyright as the checker/LSP. Which means I use a good-enough-but-not-great plugin which makes pycharm use pyright instead of the buggy heuristic based built in type "engine". And this is noticeable slower, which is part of my motivation for upgrading.
Other part is to be able to play a few games. I could probably just upgrade my GPU, but I'm not sure if it's even possible (outdated PCI port on my MB I think) without getting something second hand.
Third part is that I want to play more with the new NLP technology which is rapidly reaching a point where it should be possible to do a lot of cool stuff. And I want as much as possible to run locally.
I had a similar CPU (i5 4690k) and it would have been good for a few more years, if not the 3080 I once bought after a fight with my wife. Old CPU was just slowing it too much.
