It isn't really about performance though is it. Simply nice to keep old hardware running for the lols sometimes, other times simply because no matter how new kit benchmarks old kit still does the job.
My daughters in Primary school, her current PC is an old Q9550 with 8gb of DDR2 and an HD5750 1gb passive GPU, it serves her well for learning her way around a pc, school work, etc, runs Windows 10 and has SSD storage. It plays her age group games and some of the basic titles popular with her age and with a 1050ti can do a bit more.
A 650w psu is still overkill.
Now compare that to some in these forums running top spec computers with massive over specced hardware with enough RGB to light up Brighton Tower. Many would be just as well with an i3 and 16gb memory with a 3060ti but no, i9 360 AIO, 8 case fans, 64gb memory and a 3080ti to play pubg and fortnight with netflix and youtube.
My daughter can have my old 4770k when I change. Not falling for next gen 48 core/96 thread cpu with 256gb DDR8 at 9000mhz wiyh a 7000 series gpu that requires eight 8 pin connections and a 6000w psu with xray self tanning RGB and esp direct to brain storage solutions along side the 400tb M48 drives required for future tripple AAA 40tb download games.
Still not seen anyone actually utilising their hardware at home. Even at work our daft spec PC custom built for 4k media and youtube content got replaced with a laptop that does the same job while being mobile.
Will continually use and recycle old hardware until it simply cannot be used.
