How to tell CPU health - Interested in buying a used CPU

working on my first ever build and want to make sure I am not buying crap. This is for the: i7-875k. Seller has provided these images:
https://gyazo.com/fba4cb084f9b54627267c726579e9502

Claims that the CPU was never overclocked. Claims max temperatures hit 70-80 under large load.

Getting this for a fairly good price, with compatible Intel DP55KG mobo, cooling fan and 8gb ram included.

This is for a rly small budget build (~275). Plan to add a gtx 1050 mini to it brand new which is most of the cost. Can any1 verify if this cpu is in good health, what further information regarding it I should ask, and will this old mobo work with my 1050?

Thanks!!

This is what the build will look like (already own the 850 evo):

You really don't need any more info. A CPU is a CPU. They rarely go bad and rarely fail. They are generally one of the safer used items to buy.

Cpu performance degradation is not a thing in cpus. If it is working it will perform as it always has.

What is a thing is voltage degridation, which is where the cpu has to have higher voltages to be stable at the same clockrate, but this only happens under extreme overclocking and voltages higher than any sane person will use for daly use.

A modern cpu will always shut itself off before reaching damaging tempratures. Cold shock can crack contacts under the die, but that only happens with nl2 cooling (once again extreme overclocking)

overall buying a used cpu is pretty safe as it can be very hard to damage it under normal usage.
