Last time I sent a Core i7 2600k to RMA, I'm also get a called from Idealtech, they ask me to top up not sure RM100~200 for Core i7 3770k because they say Core i7 2600k already discontinued. Sometimes, we also depends on luck. If we lucky enough, we can use the graphic cards for more than 5 years without defective.

So far, from 10 years ago when I'm still a student. I've been using nvidia GeForce mx440, 7600GT, GTX460, GTX680 until now. My computer is still using GTX460, that card is still working well. Now I was bought a GTX1070 and make my GTX460 as dedicated PhysX. It's still working well.
