1-3 years????? it should last longer than that I've used to have a fx 8320 and that lasted me like 4 years but when I got it its was like 3 years after its launch. And my card was like r7 260x 6 years old. I could run all the games league of legends,pubg(was crappy of course love devs),overwatch,GTA 5,rise of the tomb raider,deux ex ect ect. Was on medium mostly with a few settings on high. had an r7 260x then went to r9 280 from a friend for cheap cause i needed a quick replacement at the time(r7 stopped working). And even by today's standards 1080 is a pretty solid card. That rig will last you well over 3 years but in order for it to you simply will have to adjust your settings and get really high frames. And with the game settings are going minimum gpu is like 2-3vram minimum, cpu are still way back stuck in like 2013ish. And plus if anything you can just overclock and when you do that warranty will have already expired.
