Dude, I don't overclock either. My last build is more or less 10 years, thanks to Prophecy Shop (I worked for them til they closed down).
I've been hesitant to upgrade because why spend so much dosh every year when you can get a decent build and have it last you at least up to 10 years before needing to rebuild again because of old age, wear and tear? I'm on a tight budget so I can't justify R4000 for a CPU, it's just way too much.
My Sandybridge was a quad-core - played most games very well and I had a decent mid-range GPU too. I"m not one to chase the latest technology fad and only choose what I need.
Each to his own, it's your choice and your money, you pay for what you get.
