Gaming PC upgrade order: what to upgrade first

A practical upgrade order based on common bottlenecks and failure points. There are no product prices here, just the decision logic.

The guide

  1. Storage: if you're still on a hard drive, an NVMe SSD is the biggest felt improvement per pound.
  2. Power supply health: an ageing, unbranded PSU should be replaced before a GPU upgrade, not after.
  3. GPU: the main lever for frame rate at 1080p and 1440p.
  4. RAM: go to 32GB only if monitoring shows you're running out.
  5. CPU/platform: last, because it usually means a new board and RAM too.

Always check PSU connectors, case clearance (GPU length) and PCIe generation before ordering.
