PC Build Guide 2026 — How to Choose the Right Spec

Building or buying a gaming PC in 2026 is both easier and harder than ever. Easier because the component landscape is well-established — the RTX 5000 and RX 9000 series are mature, AM5 and LGA 1851 platforms are well-supported, and DDR5 is universal. Harder because the choice of components at every price point is genuinely competitive. This guide gives you a clear recommended configuration at every major budget tier for the UK market.

Building to a tight budget? Our AMD Ryzen 5000 (AM4) PC builder uses DDR4 memory and AM4 motherboards from £46, so it is the cheapest way to get a brand-new custom PC from us — same 3-year warranty, same free next-day UK delivery.

Component Priorities — What to Spend on First

If you need to make trade-offs within a budget, here's the order of priority:

  1. GPU — This drives gaming performance more than anything else. Don't compromise here.
  2. CPU — Match it to your GPU tier. Overspending on CPU at the expense of GPU is a common mistake.
  3. RAM amount — 32GB is the minimum for 2026. Don't go below this on a new build.
  4. Storage size — A larger NVMe SSD saves headaches. 2TB is the practical recommendation.
  5. RAM speed — DDR5-6000 is the sweet spot. Beyond this, the gains are marginal.
