How we filter

Every feed has its own filter, tuned by hand for this one part. Before any change goes live, those filters are tested against thousands of real eBay listing titles. Every night, each feed is checked against every other deal page in its category, so a listing for a different part that slips in gets flagged and fixed instead of quietly shown.

Of the 78 listings we observed for this game in the last 30 days, we filtered out 55 of 78 (~71%) for quality reasons. The remaining 23 are what we'd actually surface.

  • 35 matched a bootleg / out-of-scope keyword
  • 7 priced below our floor (too good to be true)
  • 6 caught by a junk-listing guard
  • 4 seller had too few feedback ratings
  • 2 seller positive-feedback percentage too low
  • 1 priced above the curated ceiling

What the feed excludes

An eBay search for Intel Core i7-8700K returns far more than the part itself: laptop chips, mining rigs, coolers, empty boxes and whole PCs all mention it in their titles. These are the 65 terms we filter out to keep this feed to the real thing. A listing whose title contains any of them never reaches the feed, the price table or an alert. Many look unrelated to Intel Core i7-8700K because they are: that's the noise.

Core i7-8700K: buyer & reseller spec sheet

Exact SKU identity. The 8700K is a 6-core, 12-thread unlocked desktop processor for the LGA1151 socket. It sits next to the non-K 8700 and low-power 8700T, which are different purchases, and the feed excludes those by title. Used listings often quote the S-spec SR3QR, a handy cross-check against the markings on the heat spreader in the photos.

Variants & value impact. Retail boxed copies (BX-prefixed part numbers) and loose pulled chips both show up. Loose chips usually come without a cooler or packaging, and the original box is one source of the asking-price spread. Open box listings are counted with New on this page, so read the description to see whether the chip was installed.

Listing traps. Engineering samples ("ES", "QS" and similar codes in the title) are titled like retail chips but are not the same product, so the feed drops them. Motherboard-plus-CPU combos, prebuilt PCs and multi-model "compatible" listings also carry the 8700K name as the headline part. They are excluded by title wording and the price ceiling. If you are weighing it against the Core i7-9700K, confirm your motherboard's BIOS support for the exact chip before buying.

Buying a used processor: what to check

These checks apply to every processor on our CPU pages. The item notes above cover what is specific to this model.

Used

  • Ask for a clear, close photo of the pins or contact pads, wherever the socket keeps them. Bent pins are the most common failure.
  • Confirm the model printed on the heat spreader matches the listing, and ask for a screenshot of the chip identified in the OS or BIOS.
  • Ask whether it was overclocked or delidded. Neither is a dealbreaker, but both should be disclosed.

Refurbished

  • Find out who tested it and what the return window is.

New

  • Check whether it is a boxed retail chip or a tray chip. Tray chips usually ship without a cooler and with a different warranty.
