We Priced 20,000 Prebuilts. Only 1.2% Beat DIY.
I built a tool that does one thing: it compares every prebuilt gaming PC in our catalog to what its parts would cost if you bought them yourself at current US retail prices. GPU, CPU, RAM, NVMe, motherboard, PSU, case — all of it. The number on the product page is real, computed against today's prices.
After running it across 20,710 scorable listings — every prebuilt we track from Walmart, Amazon, Newegg, Best Buy, and Microcenter — here's the result:
Only 1.2% of prebuilts are at parity with DIY or cheaper. The other 98.8% are paying more for the prebuilt than the parts cost on their own. The median listing carries a $1,220 markup over DIY.
That number is way bigger than I expected. Going in, I figured prebuilts ran maybe $200-400 over DIY on average — the cost of assembly, warranty, and OS license, basically. The actual data says no, it's way worse than that. And the spread is wild.
The distribution
Here's how every listing falls out:
| Markup | Listings | Share |
|---|---|---|
| Cheaper than DIY | 89 | 0.4% |
| Within ±$50 (parity) | 161 | 0.8% |
| $50–200 over | 1,096 | 5.3% |
| $200–500 over | 4,602 | 22.2% |
| $500–1,000 over | 2,778 | 13.4% |
| $1,000–1,500 over | 4,044 | 19.5% |
| $1,500–2,500 over | 5,293 | 25.6% |
| $2,500+ over | 2,647 | 12.8% |
The fattest band is $1,500-2,500 over — 25% of the entire market. One in eight listings is overpriced by $2,500 or more. That's not a typo.
The two peaks are interesting. The $200-500 hump is mass-market mid-tier prebuilts (think SkyTech, iBUYPOWER, HP Omen at $800-1500). The $1,500-2,500 hump is premium-tier and boutique territory — Maingear, Falcon Northwest, Origin, anything with "Elite" or "Legion" in the name.
The 1.2% at parity or cheaper isn't a typo either. It's a real, actual minority of the market. Three configurations on this whole site beat DIY by more than $300.
By retailer
The retailer split tells a tighter story. Median dollar overpricing:
| Retailer | Median over DIY |
|---|---|
| Microcenter | $9 |
| Best Buy | $490 |
| Amazon | $520 |
| Newegg | $1,361 |
| Walmart | $1,502 |
Microcenter is alone in a category. Their PowerSpec house brand is sold at near-parity with DIY parts cost — the median is $9. That's not a margin. That's a loss-leader strategy. Microcenter uses prebuilts to draw shoppers into the store, where the actual margin lives in the peripherals, monitors, accessories, and upgrades you pick up on the way out.
Best Buy and Amazon are roughly tied around the $500 mark. Reasonable but not exciting.
Newegg and Walmart are double-trouble territory. Newegg is mostly its in-house ABS / iBUYPOWER configurations, plus boutique listings. Walmart is mostly third-party sellers, and a lot of those listings are aggressive markups on builds with mid-tier components.
If you're shopping by retailer, the hierarchy is real: Microcenter (if you can drive there) → Best Buy/Amazon → maybe Newegg → don't bother filtering Walmart by anything except PC/$.
Where the deals actually live
The 1.2% at parity or better isn't randomly distributed. It's almost entirely:
- Microcenter PowerSpec configurations (pickup-only, but real)
- Aggressive flagship-tier deals at Newegg/Best Buy when GPU bundle pricing kicks in
- Open-box and clearance at Best Buy when CyberPowerPC SKUs reach end-of-cycle
- Walmart third-party clearance in rare instances
It's almost never a boutique vendor. It's almost never a "gaming"-branded direct-to-consumer SKU. It's almost never the listing at the top of a "best gaming PC under $X" affiliate listicle.
What this means if you're shopping
Sort our catalog by PC/$. The score is purely the ratio of prebuilt price to DIY parts cost. Higher score = better deal vs. building it yourself.
Filter to your GPU tier on find a build, look at the top results, and check the DIY breakdown on each product page. If "Cheaper to build" shows a small or negative number, you're looking at one of the rare ones. If it shows $500+, you're looking at the median.
Why I wrote this tool in the first place
Most "best gaming PC" affiliate sites have an obvious incentive: the more clicks, the more revenue. They don't ask "is this a good deal" — they ask "will this rank for the keyword." The answer to "is the typical prebuilt a good deal" turns out to be no, and most affiliate sites would rather not say that out loud.
I'd rather be honest. The 1.2% are real and they're worth buying. The other 98.8% are markup. Sort by PC/$ and you'll see exactly which is which.
If you want to verify any of this on a specific listing, paste the URL into the analyze tool — it'll show you the full DIY parts breakdown alongside the prebuilt price. The math is the same one I ran across all 20,710 listings to build this distribution.
