I just upgraded an Athlon64 x2 to a Phenom II x4 because I could get the chip for $20 and a cooler for $30. Heck of a speed boost on that box, which was looking a little long in the tooth otherwise.

It's now beefy enough to run a modern OS and GUI and even do some light gaming on, but the mobo has serial and parallel and PATA and floppy ports so it serves as my media archiving mule too.

I ran a Phenom II x4 DDR2 until this summer when I bought a Ryzen 3700X. It could not play Battlefield, Rainbow Six Siege, Squad, Far Cry, Pubg ( could almost play, loading stream time was the killer), Mordhau and the likes, but it could play a lot of games, so many that I didn't need to upgrade, it was the computer as a whole that was giving up.

I could play Wargame Red Dragon, Dark Souls 3, Dota2, Dishonored 2, Remnant from the ashes, Warhammer 1 total war, Disco Elysium, Dragon Age Inquisition, Fallout 3 New Vegas.

I'm using a AMD Athlon II X2 260, released in 2010.

I'm still running an Ath 64 x2 6000+ for a web server, I think it's from about 2006. That with an old hard drive are running 120W, which would be nice to hack down.

I don't remember if I jumped straight to this from my Pentium Pro 200, but the role of this box started with that one.

Athlon 64 was the bomb at that time

Yeah I had one of those. It was great but so noisy.

Then Core2, then i5. I built my son a computer last year on Ryzen and it's great, but I don't see myself upgrading my i5 for a couple of years. My money will go on GPU upgrades (currently a 1070) instead I think.

My Athlon is in a case next to my left knee. I was almost scared off by the Intel hyper but not too sure of AMD spin. We're all casualties of marketing departments. In the end I bought AMD because it was cheaper than Intel.

I ran one of those until a couple years ago when I got the 2400G APU. What a nice upgrade. Even better parts available now.
