FX 5200
8400 GS
These two were when I was growing up, and mostly played on consoles. Good enough for more basic games. Did play stuff like Fallout 3, Borderlands, and Spore on the 8400 GS though (lol).
GTX 960
GTX 980 Ti
Been tempted to upgrade to a RTX 2080 Ti, but now I'm waiting. Dunno whether to wait until next year with the likely 3000 series release, or until the rumored 2080 Ti Super drops... 980 Ti is still working well though—can still max out most games at 1080p, and it handles a decent number of games well at 1440p and 4K. Would like to run pretty much everything at 4K though. Also have a large Steam backlog to work through, and those older games run really well.
