My home workstation is going on 10 years old - an i5-750 w/ 8GB of memory and a positively decadent - and silly - SLI arrangement on the graphics accelerator (got the cards for free a few years ago, necessitating a beefy PSU). While today’s 10 year-old workstation isn’t as intolerably long in the tooth as the same situation 10 years ago, it’s still aging.
I confess to being tempted by the brute-force power computing power that the new-ish AMD Threadripper chips offer. With the present rate of change, such a platform could remain viable for another 10 years, properly equipped. But I’m also not gaming anymore with consistency and conveniently forgot to install a torrent client on the present rig.
