How long will this build last me

[hipieliedie3]

What should I change and how long will this build last me. (How long will I be able to play new games on med-high) I also know there is no certain way of knowing how long it will last but still I'm VERY curious.

I5 6500
Gtx 970 Asus Strix (I know about the Rx 480 and gtx 1060 but I happened to already get the gpu because my dad's brother gave it to me because he got it as an unwanted gift)( He has a 980 so he doesn't want it)
MSI B150 Gaming M3 Mobo
HyperX Fury 2x4 gb DDR4 Ram
SSD 250 gb Samsung 850 evo
Corsair Carbide Spec - 02
500 watt EVGA PSU 80+ Certified
Internet by Ethernet Cable ( I know that has nothing to do with fps/ graphics just connection speed)
2 Extra Corsair fans
Another 2 come free with case

Thank you for all input in advance.

If your criteria is med-high, presumably at 1080p res, you're good for a while probably.

Plus you got the GPU free, so why are you even worried? Don't look a gift horse in the mouth, just enjoy it and be thankful you have it.

I'm not worried and I am thankful, believe me. I'm just super curious, I've been looking for someone asking for this question at around the same rig but I could only find people with Gtx 980 ti, I7 6700k, Z170 Mobo etc. Eventually I decided to make my own post
