By virtue this is nice and noble. But objectively you're likely not doing you a favor. To answer your question, and to also give you an example: In early 2020 I passed my 2012 Xeon machine down to my SO to replace her 2007 Celeron. Technically, the machine was "good enough" for what I did, but for WFH I needed more RAM if I wanted to avoid VNCing (via VPN) into my office computer to do my work - which really annoyed me. Upgrading 4x4GB DDR3 to 4x8GB DDR3 would have made no economical sense (even used), so I switched to AM4 (MB/CPU/RAM). Because I hate waste I already planned for a future upgrade path (= decent mainboard) and got a really cheap Ryzen 1600 AF (still 50% faster than my old CPU) instead of a more expensive 2800X. Back then I planned to eventually get a 3800 (wasn't released then), now the 5800X or better are an option. That was for work. The machine is actually my personal computer (work data is encrypted on Linux), so that also does gaming duty (got new GPUs 2007, 2014 and now 2021; old GPUs have been passed down to family/friends). For hobby I still have a 2009 Xeon in the NAS (got it from a friend), which will probably inherit the Ryzen 1600 CPU once I upgrade the desktop. For the sake of your eyes: Get a decent TFT. Also more screen estate will make you more productive. I usually recommend 2x27" WQHD or 4k for pure work stuff. At home I use 1x34" UWQHD instead (because two screens are not good for gaming).
