Has either machine died? No? I think you are taking this the wrong direction. Besides, your gaming rig is outclassed? I guess that depends on your idea and what you think you need. Will it still play most games? Just cause something cant do it at max resolution does not mean it failed. What you posted has NOTHING to do with quality. They built quality cars in the 50s, they still can do the job, they are just obsolete.
...and your post ignored the parts you didn't want to see. I listed two machines that still work
for what they do just fine (the second one qualified with, "if I could stop tinkering with it" - which I admit is all me) Hell, one of them I said that i even built out of spare parts showing that they
were quality and I've been able to stretch their use.
As for the gaming rig - of newer parts - yes, parts of it
are starting to fail, as does happen with heavy-use performance PC parts these days. Hard drive is getting bad sectors and isn't read/writing as fast (the clicking begins), GFX card is running a lot hotter than it used to, and there are a few parts that I've replaced. Performance companies know that you're going to upgrade in 5 years or less, so parts are designed with planned obsolecence...so, yes, I'd say that fits exactly in to this conversation.
