Reasonable price for used i7-3770K and i5-3570K?

Hi everyone,

I was hoping someone could help me price two old CPU's I have. I recently upgraded my system and no longer have a use for either of these CPU's. I have a co-worker interested in buying both of them, but I can't figure out how much I should charge.

Both CPU's have 2 years of use. I have the original packaging for both as well as the stock coolers. Also, I'm not sure if it makes a difference, but I never overclocked them.

Any ideas?

Thanks in advance for helping! In addition, let me know if you require more info.

Expect to get prices of between 100-160 for the 3570k, and 220-320 for the 3770k (going off of Ebay.com, USD prices).

I would expect to get 75-90% of the new price for an equivalent skylake part tbh

Yup about 75% of the new part seems about right (considering there's not much difference performance wise)

Thanks for the info guys! I'll shoot my co-worker an offer Monday and see if he'll take it. It will be nice to make some money back on these.
