I was wondering when people consider themselves to have a new PC. Technically I’ve had the same PC for close to 20 years now, but every part’s been upgraded several times over.
I figure everyone’s got a different mind about it. For me, I’d have to say when all of the big three—CPU, GPU, mobo—have completed a phase, my brain thinks of the previous setup as “the old PC”.


Definitely when I upgrade the mainboard + CPU, which usually also means new RAM. It’s pretty expensive, you have to change several parts in one go and it’s much more noticable in general usage than the GPU.
To me thats the line. Unless you are like, a very active enthusiast, most people, once they get their CPU installed cooler installed, etc… you probably aren’t’ swapping that out. Its pretty much a computer at that point.
