Personally, I’m playing on a laptop that I bought in 2020 and it runs everything I want it to run no problem, and I’m planning to change it only when it breaks irreparably.

Look up a YouTube video on how to disassemble it and clean out your fans and radiators. Then replace your CPU/GPU die thermal paste along with thermal putty and you can greatly extend your laptop’s lifespan. I also have a gaming laptop from 2020 and doing this dropped average temps significantly (somewhere around 10-20 degrees), and on my device the teardown was pretty simple. I used Honeywell PTM 7950 on the CPU/GPU dies and and upsiren utp-x ultra putty for my VRAM and VRMs. You will need 91% iso alcohol and some paper towels for cleaning existing paste and ideally compressed air for blasting out stubborn areas of dust, for this I use a rechargeable air duster but canned air and air compressors work great too.
