Yes, that's fair, but if you're considering a potential fx8350 for $50 second hand to slot into a current computer setup, compared to purchasing new motherboard and an intel cpu, considering you're still likely to get playable frame rates in most titles... The fx8350 is still okay as a low end gaming processor.
I know because i've got one. Yes, compared to my modern i5 it lags behind in FPS... but it's still over 30fps in MMO's like Tera/WoW and over 50fps in most 1920x1080 titles.
Would i recommend buying one new in 2017? Hell no. But if you can get one on the cheap why not?
Edit for clarity - I use a GTX 970, but have also tried it with an R9 390.
I have a friend who's rig is fx8320 and GTX 960 and it still games on medium-high...
