Hello, I have a Core i5-6600k with the PCB scratched pretty badly from what I can tell. I don't know how it got like that, it's not mine. I was sure it was dead and I was ready to throw it away but I decided to test it on a mobo just in case and the thing is it actually works. I'm using it in my main PC right now instead of my i7-7700k, writing this post, YouTube playing, some programs and Office docs open in the background etc. Been using it for a few hours now and even tried it in Overwatch, PUBG and CoD WWII along with my GTX 1070 and it works perfectly. Slightly lower fps than using my i7 but very little difference and that was expectable.

Here's the link to the pictures of the CPU, please take a look.: https://imgur.com/a/oORnV
My question is, do you think those missing "connectors" or whatever those rectangular things in the middle of the PCB are can have any sort of long term damage to how the CPU works? Will I be able to sell it for some cash or give it to a friend to use without thinking that it will fail really soon?
I don't even know how it still works but hey, it's amazing.

Thanks a lot!

 
Solution
I would say that if it is working normally now that it will continue to do so. I don't see that it will affect the longevity.

Usually if damage is sufficient to cause an error, it does so right now.
