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 47 of 78 (~60%) for quality reasons. The remaining 31 are what we'd actually surface.
- 27 matched a bootleg / out-of-scope keyword
- 9 priced below our floor (too good to be true)
- 6 seller had too few feedback ratings
- 3 shipped from a region we exclude
- 1 seller positive-feedback percentage too low
- 1 caught by a junk-listing guard
What the feed excludes
An eBay search for Intel Core i9-9900K 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 i9-9900K because they are: that's the noise.

Core i9-9900K: buyer & reseller spec sheet
Exact SKU identity. The 9900K is an 8-core, 16-thread desktop processor for the LGA1151 socket, with integrated graphics. Its name nests inside the 9900KF (no integrated graphics) and the 9900KS, which are different purchases; the feed excludes both by title. Confirm the model on the heat spreader in the photos, not only in the title.
Variants & value impact. Retail boxed and OEM or system-pull chips both appear. A pull usually ships without a cooler or retail packaging, and the original box is one source of the asking-price spread within Used. Open box listings are counted with New on this page, so read the description to see whether the chip was ever installed.
Listing traps. Engineering samples ("ES") sell under the same name and are not retail chips; the feed drops them by title. Whole PCs, laptops, all-in-one iMacs, and CPU-plus-motherboard bundles list under this CPU's name as the headline part; they are excluded by title wording and the price ceiling. Multi-model "9700K 9900K 9900KF" titles are catch-all listings, not a single 9900K. Ask for sharp photos of the pin-side contacts and confirm your motherboard's BIOS supports the chip.
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.
