Hey guys!

Say I have CPU A and CPU B. Will they last the same or will one last longer?

CPU A:
Stock Everything

CPU B:
4 ghz
Same Voltage

How would the life compare between the two?

Also, what should I overclock my i5 4670K to?

hard to say because CPU A and CPU B could not be identical off the start, which most CPU's aren't. I know with AMD CPU's anyways, they all have a slightly different stock voltage, so they are different off the start regardless of overclock.

Does overclocking work the CPU more during full load, yes. Do people run their CPU's at 100% 24/7, no. You also have to figure in, that CPU A, in a basic persons's system with stock cooler and 1 rear case fan that came with it, will run at temp XX. Overclockers tend to overdue their cooling, so even though they are running faster, the heat of the chip is the same. I have my 8320 AMD chip, stock 3.5, running at 4.6ghz. I have 4 massive case fans, liquid cooling CPU, fan shroud blowing cool air directly on the socket area, etc, so even though I am overclocking 1.1ghz over stock, my temps are lower than stock temps with stock cooler.

So theoratically, if every cpu was the same, they would last the same amount of time?

if you kept them both cool, under their thermal limits, used a good motherboard that has good voltage regulators to keep voltages from straying and weren't running both system 24/7 for 2 years running prime, yes, they should both be ok. This is providing it's not crazy overclocking with massive voltage increases, etc.
