That's the other thing. Even if my motherboard/PC developed a fault I'd either try and get another X99 based setup. Even if the CPU couldn't be reused, or it wasn't cost effective to source a mobo, I'd still just buy a budget CPU/mobo to re-use the DDR4 RAM/etc as I simply don't need any more CPU power.
Looking back it's actually shocking how little CPU performance has improved in the past 12 years since Intel released the i7-series back in 2008. I guess a modern Ryzen is probably ~4 times the performance of an i7-920 in multi-threaded apps but I suspect that just doesn't translate into a noticeable difference in most use cases.
