So a very long time ago now, I upgraded from my ancient AMD FX 6100 to a Ryzen 5 1600, and now I am on my 3rd CPU with an Intel i3 12100f.
Why did I go with an i3 and not the i5? Simple, I was on a budget and I couldn't justify spending more than $250 CAD for this upgrade. I could've squeezed in the 12400 if it was in stock, but it wasn't.
Why didn't I just get a new AMD CPU and slot it in? Well I tried, but my Gigabyte motherboard (even with updates) refused to play nice with the 5500 I tried to upgrade too. If I was keeping with AMD I'd need to buy a new Motherboard and if I was buying a new Motherboard for this I might as well get the best bang for my Buck.
So what did I get.
Motherboard: MSI PRO B760M-P since it had the IO I wanted (2x M.2 slots and a USB C Port on the back)
CPU: Intel i3 12100f
And the results are... honestly surprising. Despite loosing 2 core and 4 threads, I gained in performance everywhere, or I was GPU limited with my 3050. 2 minutes off of my 10 minute handbrake render, 50fps extra in Doom 2016, and a doubling in Geekbench single core performance which I need thanks to my work in FreeCAD. FreeCAD is still slow, but the models I am loading are demanding.
Overall I am happy with my upgrade, and the best part is, since I am buying my Motherboards at the end of a socket generation rather than the beginning, it means when I want to upgrade in a few years, it should work with intel 13th and 14th gen CPU's.

I just upgraded my cpu in a long time too! Everything that could go wrong, did. I had to flash my bios a few times, straighten some pins, clean out some thermal paste from the socket, but after 3 days I figured it all out and got it working. Getting a build working after lots of problems is so fulfilling, it's almost worth the years of life I lost from stress.
I didn't have to do that. Bought my parts from Canada Computers and they open the Motherboard box in store before the sale, to inspect it, and I had to sign off on it.
That said I had some issues of my own design. My PC has a space for a 3 1/2" floppy and I wanted it internal so I got a USB adapter for it to run off of the internal header. The damn board locks up on boot if its in.
Probably a setting but still annoying
I feel your pain. 9 years ago I dropped my Intel CPU into the socket. One magnifying glass, a tweezer, some toothpick, and a week later it was up and running for 8 years, until I moved and leave it in a cardboard box for 6 months. Now it's just boot looping after the CPU fan spin for a few seconds.
