Best Place to Buy Used PC Parts in the UK — eBay vs CeX vs Gumtree, Tested
Three months of price data comparing eBay UK, CeX and Gumtree for used GPUs, CPUs and RAM. Which marketplace actually has the cheapest PC parts in 2026?
Every PC builder asks the same question: "Where's the cheapest place to buy a used GPU in the UK?" We tracked 14,000+ listings across eBay UK, CeX and Gumtree over three months and ran the numbers. Here's the honest answer.
TL;DR
- Cheapest average price: Gumtree (collection-only)
- Best for grading and warranty: CeX
- Widest selection and lowest absolute prices on auctions: eBay UK
- Most "Steal"-flagged listings: eBay UK (by a long way)
No single marketplace wins outright. The right answer depends on what you're buying and how much risk you'll absorb.
Method
We pulled every active listing for the top 30 UK-traded PC components — GPUs, CPUs and DDR4/DDR5 RAM — and tracked their prices against the rolling 30-day market average. "Cheapest" below means median price as a percentage of market average.
eBay UK
The deepest pool. About 70% of all UK used-part listings live here.
- Median GPU price vs market: 102%
- Median CPU price vs market: 98%
- Median RAM price vs market: 105%
- Where the steals are: Auctions ending on weekday mornings. Sunday-night auctions consistently close 8–12% above market — avoid bidding at peak times.
eBay's Buy-It-Now pricing is usually above market because sellers price to where the auctions close on a busy Sunday. The arbitrage is to buy in the off-peak window and sell at peak.
CeX (uk.webuy.com)
Fixed-price, graded, 2-year warranty. The "safe choice" — and sometimes the cheapest.
- Median GPU price vs market: 108%
- Median CPU price vs market: 112%
- Median RAM price vs market: 118%
- Hidden edge: When the market jumps (new GPU launch, crypto pump), CeX prices lag by 5–10 days. During that window CeX is briefly the cheapest place in the UK for older-gen cards.
If you want zero hassle and a warranty, CeX is your default. If you're price-sensitive, treat it as a benchmark, not a buyer.
Gumtree
Collection-only listings only — distance-shipped Gumtree listings are mostly scams.
- Median GPU price vs market: 88%
- Median CPU price vs market: 91%
- Median RAM price vs market: 95%
- Catch: You need to be near a city. London, Manchester, Birmingham have 5–10x the listing volume of smaller cities.
Gumtree wins on price because sellers want cash today and discount for convenience. The trade-off is the drive, the no-show risk, and zero buyer protection. Pay cash, test on a borrowed PC at the seller's flat, and never wire money in advance.
Which is best for each part?
| Component | Best marketplace | Why |
|---|---|---|
| Used GPU (high value) | eBay UK auctions | Widest spread, biggest savings on a £300+ purchase |
| Used GPU (low risk) | CeX | Warranty matters more when there's no recourse |
| Used CPU | eBay UK Buy-It-Now | CPUs rarely die; warranty is overkill |
| Used RAM | eBay UK | RAM is cheap enough that fees don't matter much |
| Anything if you live in a major city | Gumtree | Always check first — collection prices are 10%+ cheaper |
The real answer
Stop choosing one marketplace. The cheapest GPU in the UK on any given day is on a different site every day. The only sane strategy is to monitor all three at once.
That's exactly what PartSnipe does. We index eBay UK, CeX and Gumtree every 30 seconds and rank every GPU, CPU and RAM listing by how far below the rolling UK market average it is — so you never miss the moment one marketplace temporarily becomes the cheapest.
