I still happily develop on an i7-950 with 24GB of RAM from 13 years ago. I just haven't been able to justify the minimal performance improvements from upgrading vs all the other things my family needs.
Nope, that machine has a 512GB SSD and runs just as fast as modern corporate dev spec laptops I've used with the same core count. That being said, my static analyzer would definitely benefit from a more modern CPU!
