My old girl has been running more or less on the components I got for her in 2011. Heck, the main HDD is much older than that. I think the newest part is the RAM which I got a year or two ago, but the CPU, Mobo and GPU are all 2011 stock and they're still holding up alright.
I won't run GTAV on max settings (or quite possibly at any settings) but it works for what I want it to.
Of course, now I've typed this something will probably explode.
