Every week we speak to first-time buyers who've spent hours researching and still feel lost. CPU cores, VRAM, NVMe, RAM - the spec sheets read like a different language.
This guide cuts through it. We build custom gaming PCs every day, and we see the same mistakes made repeatedly. Here's what you actually need to know to buy the right machine, at the right budget.
Start with the games, not the specs
What do you actually want to play? This sounds obvious, but most buyers skip it and end up either overspending on power they'll never use, or underspending and being frustrated by a machine that can't keep up.
Lighter games - Fortnite, Minecraft, Roblox, Valorant, Rocket League. These are well-optimised and don't need a monster PC. A good budget build handles all of them comfortably at 1080p with smooth, high frame rates.
Demanding games - Cyberpunk 2077, Battlefield 6, Elden Ring, Starfield, AAA open-world titles. These push hardware hard and reward a more capable GPU. If this is where you're spending your time, spending more on the right build pays off.
The honest rule: figure out which games you'll actually play first, then match the hardware to those.
The biggest factor: Graphics Card
The graphics card (GPU) is the engine of your gaming PC. It is the single component that determines how well your games look and run. Everything else exists to support it.
Many builds pair impressive-sounding processors with weak graphics cards. The result underperforms in every game, regardless of how good the spec sheet looks.
Here's a real example that shows exactly where your money does more work:
GPU Comparison: RTX 3050 → RTX 5060
RTX 3050 is ideal for 1080p gaming, The RTX 5060 can handle 1440p 
At 1080p, the RTX 3050 is a capable and cost-effective choice — handling lighter and mid-range titles smoothly without breaking the budget. The RTX 5060 is a significant step up — comfortable at 1440p and, with Frame Generation, capable of enjoyable 4K gaming in supported titles.
RAM - 16GB is the floor, 32GB is comfortable
RAM is your PC's short-term working memory. Modern games combined with Discord, a browser, and background apps regularly push past 12GB. 16GB DDR4 is the minimum we'd recommend in 2026. 32GB gives you proper headroom.
Storage - SSDs are needed in 2026
An SSD is now essential for modern gaming, this is why we wont spec a Gaming PC without one. The difference between an SSD and a traditional hard drive isn't subtle - games load dramatically faster, the system boots in seconds, and the whole experience feels sharper.
CPU — good enough is genuinely good enough
For gaming, you don't need to spend big on a CPU. A modern 6-core processor like the Ryzen 5 5500 paired with a strong GPU handles everything on the market today without issue. If you plan to stream simultaneously, an 8-core chip makes a noticeable difference — but for pure gaming, it's often not worth the extra spend.
What your budget actually gets you
£400–£600 · The capable entry point
Handles the most popular games well -Fortnite, Minecraft, Roblox, Valorant, and Rocket League all run smoothly at 1080p with strong frame rates.
Example build: WJMTech DS — £589.99 Ryzen 5 5500 / RTX 3050 6GB / 16GB DDR4 / 512GB SSD + 1TB HDD / 3yr Warranty View the WJMTech DS
£700–£1,100 · More demanding titles & higher resolutions
Builds at this level are equipped for the most demanding titles at 1440p and 4K — with Frame Generation doing the heavy lifting
Example Build: WJMTech Vision — £1,049.99 Intel i5-12400F / RTX 5060 Ti 8GB / 32GB DDR4 / 1TB NVMe / 360mm AIO / 3yr Warranty View the WJMTech Vision
Comparing the price points
Here's what two of our builds actually deliver across popular titles at 1080p. These are representative real-world figures based on benchmark data.
| Game | Settings | £589.99 WJMTech DS (RTX 3050) | £1049.99 WJMTech Vision (RTX 5060 Ti) |
|---|---|---|---|
| Fortnite | High / DLSS | ~100 FPS | 200–300+ FPS |
| Warzone | Medium–High | ~65 FPS | ~160 FPS |
| Minecraft | High | 120+ FPS | 300+ FPS |
| Cyberpunk 2077 | Medium | ~50 FPS | ~93 FPS |
| Apex Legends | High | ~90 FPS | ~170 FPS |
Figures are representative real-world averages at 1080p. Fortnite figures for the RTX 5060 Ti include DLSS Performance Mode. Actual performance varies by in-game settings and system configuration.
What to avoid
⚠ Big-brand prebuilts with weak GPUs
Strong CPU, weak graphics card — it's the oldest trick in the book. Always check the GPU before anything else. It's where corners get cut.
⚠ "Gaming" labels on old office machines
An RGB case doesn't change what's inside. If a machine under £400 is being marketed as a gaming PC, check the GPU model carefully before buying.
⚠ HDD as primary storage
Slow boot times, slow game loads, sluggish overall experience. An NVMe SSD is non-negotiable in 2026.
⚠ Forgetting about the monitor
A 60Hz display limits you regardless of how powerful the PC is. Pair any capable build with at least a 144Hz monitor — the difference in smoothness is immediately obvious.
Custom built vs big-outlet prebuilt
Big-brand prebuilts aren't bad products — but they're built at scale, with component selection driven by cost and margin. The GPU is consistently where corners get cut.
A custom build is different: every pound goes where it produces the most performance, with components chosen to work together rather than hit a price point. At the same budget, a properly balanced custom build outperforms a branded prebuilt almost every time.
How WJMTech works
Every machine we build is assembled by one person — from component selection through to testing and packaging. That same person remains reachable by phone or email long after delivery, with full knowledge of exactly what went into your build.
We're a small team. We build each machine individually, stress-test it, and back it with a 3-year warranty. If something ever isn't right, you're speaking to the person who built it — not a ticketing system.
