Around 2012 I bought a 4-core Core i5 and after some basic upgrades (max RAM to 32GB and a good SSD) it had more-than-acceptable performance for my work until mid-2018. Even when I dabbled with Machine Learning I borrowed a 1070 from my office and was plenty to run my tasks.
Around end of 2018 I started working more in different offices, so I needed a more powerful laptop. No strong offering from AMD yet, so I ended up with a System76 core i7, 6-core 32GB RAM.
2020 came and with it I got back into working at home. So I got excited about upgrading my workstation. I bought all the components to get a Ryzen 5, a 3700X I think. What a shitshow: had to go through three different pairs of RAM to find one that was actually compatible with the motherboard. Then I had to find a way to upgrade the BIOS, and I could only do it by getting an Athlon CPU. BIOS upgraded, then the original 3700 died. I ended up turning the whole system into a very expensive media center just with the Athlon and continued working with the laptop.
A couple of weeks ago my laptop's battery puffed up, so I decided to go look again into a nice desktop. An 12-core Ryzen 5900X is coming out at 900€ and a basic motherboard is 300€. 10-core Intel i9-10900 is 300€ and a motherboard for it is 180€. Guess which one I ended up taking and that I managed to get running without any issue whatsoever?
Here is to hope that in 6-8 years from now I finally manage to make the switch to AMD.
