Building a gaming PC in 2026 is more complicated than it was two years ago. The global RAM shortage — driven by AI data centres consuming memory supply — has pushed component prices significantly higher. A 32GB DDR5 kit that cost £80 in early 2025 can now cost £180 or more. That changes what each budget can realistically achieve.
This guide is honest about that. It covers three builds across three budgets, what each one can realistically play, and where the compromises lie. Prices are approximate UK retail as of April 2026 — check live prices on Scan.co.uk, Overclockers.co.uk, or Amazon before buying, as the market is volatile.
Before You Start — A Few Rules of Thumb
The GPU is the most important component for gaming. Spend as much of your budget here as you can justify. A powerful GPU paired with a modest CPU will nearly always outperform the reverse.
32GB RAM is the comfortable baseline in 2026. Modern open-world games and background apps — Discord, browser, game launcher — can push 16GB to its limits. Get 32GB if you can.
NVMe SSD only. A 1TB NVMe SSD is the minimum. Games are large, and SATA drives are noticeably slower for shader compilation and loading times. 2TB is worth the stretch if budget allows.
Don’t skimp on the PSU. A cheap power supply is the one place where cutting corners can damage expensive components. 80+ Gold rated from a reputable brand — Seasonic, Corsair, be quiet! — is the standard to hit.
Build on AM5. AMD’s AM5 socket will be supported through at least 2027, meaning a CPU upgrade is possible without replacing the motherboard. Intel’s platform roadmap is less clear right now.
Build 1 — Around £400 | 1080p Gaming
Be upfront about this: £400 is genuinely tight in 2026. RAM prices have eaten significantly into what this budget achieves compared to a year ago. The best approach at this tier is a mix of current-generation and previous-generation components, or buying a capable used GPU rather than a new entry-level one.
The Used GPU Argument
At £400, the most important decision is the GPU. A new entry-level card at this budget leaves very little for everything else. A used RX 6700 XT (12GB VRAM) or RTX 3060 (12GB) from eBay at £130–160 delivers better performance than most new cards at a similar price — and the 12GB of VRAM will matter more than an 8GB card in some titles over a three-year lifespan. Check seller feedback carefully and test thoroughly on arrival.
Suggested Components
CPU: AMD Ryzen 5 5600 — around £70–80. Six cores, AM4 socket, excellent 1080p gaming performance. Previous generation but entirely capable for modern titles. Check price on Amazon UK
GPU: RX 6700 XT 12GB (used) — around £130–160 on eBay. Alternatively, AMD RX 7600 8GB new at around £180 if you prefer buying new. The used option offers more VRAM and better raw performance for the money. Check RX 7600 on Amazon UK
Motherboard: B550 (AM4) — around £65–80. Functional and compatible with the Ryzen 5 5600. Avoid the very cheapest options; spend £70 and get something solid from MSI or Gigabyte.
RAM: 16GB DDR4 3200MHz (2x8GB) — around £35–45. DDR4 rather than DDR5 keeps costs down and is correct for the AM4 platform. Add a second 16GB kit later to reach 32GB if needed — it’s the same type and will be compatible.
Storage: 1TB NVMe SSD — around £55–70. Kingston NV3 or WD Green SN350 at this price point. Perfectly adequate for an OS drive and game library.
PSU: 550W 80+ Gold — around £45–60. Seasonic Focus or Corsair CV550 Gold. Enough for this build with headroom.
Case: Budget mid-tower — around £30–45. Airflow matters more than aesthetics. Fractal Focus or DeepCool CC560 at this price.
Approximate Total: £400–420
What it plays: Fortnite, Valorant, CS2, and most esports titles at high settings 1080p 60fps+ without difficulty. Modern AAA games at medium-high 1080p settings, targeting 60fps. Not a machine for maxing out Cyberpunk 2077 at 1080p Ultra, but perfectly capable for the vast majority of the game library at sensible settings.
Upgrade path: A new GPU is the single biggest upgrade available when budget allows. The AM4 platform also supports higher-end Ryzen 5000 CPUs if needed.
Build 2 — Around £750 | 1440p Gaming
This is the sweet spot in 2026. The mid-range GPU market has some genuinely strong options, and £750 gives enough headroom for a solid all-round build that will handle 1440p gaming comfortably in most titles.
Suggested Components
CPU: AMD Ryzen 5 9600X — around £170–190. Six Zen 5 cores on AM5, excellent gaming performance per core, and the platform supports future upgrades including Ryzen 7 and 9 chips. The best price-to-performance CPU for gaming builds in 2026. Check price on Amazon UK
GPU: AMD RX 9070 16GB — around £480–520. AMD’s mid-range Rdna 4 card punches well above its price, delivers strong 1440p performance, and the 16GB of VRAM is genuinely future-proof at this tier. Alternatively, the RTX 5060 Ti at a similar price point if you prefer Nvidia’s DLSS ecosystem. Check RX 9070 on Amazon UK
Motherboard: B650 (AM5) — around £100–120. B650 gives full AM5 compatibility at a sensible price. MSI PRO B650-S or Gigabyte B650M DS3H. No need to spend more at this tier.
RAM: 32GB DDR5 6000MHz (2x16GB) — around £130–160 at current prices. Yes, this is expensive — RAM costs are the unfortunate reality of 2026 builds. But 32GB DDR5 is the right spec for AM5 and will serve this build well for its lifespan. Check DDR5 RAM on Amazon UK
Storage: 1TB NVMe SSD Gen4 — around £65–80. WD Black SN770 or Samsung 980 Pro at this price point. Gen4 speeds are worthwhile on AM5.
PSU: 750W 80+ Gold — around £70–85. The RX 9070 recommends a 650W minimum — 750W gives comfortable headroom. Corsair RM750e or be quiet! Pure Power 12M.
Case: Mid-tower with good airflow — around £60–75. Fractal Pop Air or Lian Li Lancool 216 at this price. Both have excellent airflow and reasonable build quality.
CPU Cooler: 120mm or 240mm AIO / decent air cooler — around £30–50. The Ryzen 5 9600X runs warm under load. A be quiet! Pure Rock 2 or DeepCool AK400 at the air cooling end, or a 240mm AIO if you prefer.
Approximate Total: £700–770
What it plays: Virtually everything at 1440p High to Ultra settings targeting 60fps, and most titles at 1440p High hitting 100fps+. FSR (AMD’s upscaling tech) extends performance further in supported titles. This is a machine that will handle current and near-future releases comfortably at 1440p.
Upgrade path: The AM5 platform supports Ryzen 7 9800X3D — widely regarded as the best gaming CPU available in 2026 — as a future upgrade if gaming performance needs to step up.
Build 3 — Around £1,000 | High-End 1440p / Entry 4K
At £1,000 the build gets substantially more capable. The GPU steps up significantly, the CPU upgrades to AMD’s 3D V-Cache technology — genuinely the best gaming CPU money can buy — and there’s budget for 32GB of faster RAM and 2TB of storage.
Suggested Components
CPU: AMD Ryzen 7 9800X3D — around £350–380. The 3D V-Cache architecture delivers gaming performance that no other consumer CPU matches. It runs games faster than chips that cost considerably more, and for a gaming-focused build this is the right choice at this price point. Check price on Amazon UK
GPU: AMD RX 9070 XT 16GB or RTX 5070 12GB — around £480–530. The RX 9070 XT delivers strong 1440p Ultra and entry-level 4K performance. The RTX 5070 is a compelling alternative with DLSS 4 Multi Frame Generation support — worth considering if you’re invested in Nvidia’s ecosystem. Check RX 9070 XT on Amazon UK | Check RTX 5070 on Amazon UK
Motherboard: B650E or X670 (AM5) — around £130–160. A slightly better board to match the 9800X3D — the MSI MAG B650 Tomahawk or Asus TUF Gaming B650-Plus WiFi are solid choices at this price.
RAM: 32GB DDR5 6000MHz (2x16GB) — around £130–160. Same spec as the mid-range build — 32GB DDR5 6000MHz is the sweet spot for AM5 performance and the 9800X3D specifically benefits from fast memory.
Storage: 2TB NVMe SSD Gen4 — around £100–120. Games are large and 1TB fills faster than you’d expect. 2TB from the start is the right call at this budget. Samsung 990 Pro or WD Black SN850X. Check 2TB NVMe SSDs on Amazon UK
PSU: 850W 80+ Gold — around £90–110. The RX 9070 XT and 9800X3D together warrant 850W for comfortable headroom. Seasonic Focus GX-850 or Corsair RM850e.
Case: Quality mid-tower — around £80–100. Fractal Meshify C, Lian Li Lancool 216, or be quiet! Pure Base 500DX. All offer excellent airflow and build quality.
CPU Cooler: 240mm or 360mm AIO — around £60–80. The 9800X3D benefits from good cooling to maintain boost clocks. Arctic Liquid Freezer III 240 or DeepCool LS720 are strong value options.
Approximate Total: £1,000–1,080
What it plays: Everything at 1440p Ultra settings at high frame rates. Most titles at 4K High to Ultra settings hitting 60fps+. With AMD FSR or Nvidia DLSS, 4K performance steps up further in supported games. This is a build that should remain capable for three to four years without upgrades.
A Note on RAM Prices
All three builds are affected by the 2026 RAM shortage. DDR5 prices in particular are significantly higher than they were in 2024. If you’re building now, RAM is one area where patience might actually pay off — prices could ease in late 2026 as new manufacturing capacity comes online. If your build isn’t urgent, monitoring prices on CamelCamelCamel (for Amazon) or PriceSpy UK over a few weeks is worthwhile.

Build or Buy Prebuilt?
Self-building has traditionally been the better value option, but the RAM crisis has changed the equation slightly. System integrators who bought components in bulk before prices spiked can sometimes offer better value than buying individual components at current retail prices — particularly at the budget end. Our Best Prebuilt Gaming PCs 2026 guide covers the best ready-to-buy options if you’d rather skip the build process entirely.
