How to check a used processor? What to pay attention to? What tests?

Question

Iron

I'm going to buy a used Intel i7 3630QM. What to look for and what tests can be run?
So far I have read that the main thing is visual damage that would not be there and the legs are not rumpled.
And from the linx tests and some kind of resource-intensive game, there were cases of linx passing and then crashes in games.

Answer 1

If the computer turns on with it and loads Windows, then 99% is fine.
