Which PC upgrade should you make first?

Find the limit in your current system before replacing parts that may already be sufficient.

Step 01

Document your current system

Record the exact motherboard model and revision, BIOS version, CPU, memory configuration, graphics card, power supply model, case and monitor. Product family names alone can hide important differences.

Step 02

Describe the problem

Note whether slowdowns happen in a particular game, during exports, while opening files, or when many applications are running. The upgrade should address the observed problem and your target workload.

Step 03

Check compatibility before shopping

For a CPU, use the motherboard's supported processor list and BIOS notes. For memory, verify the DDR generation, slot configuration and supported capacity. For storage, check the actual slot interface and any documented lane-sharing limits.

Step 04

Account for supporting parts

A graphics card upgrade may require more case clearance, different power connectors and a suitable power supply. A CPU upgrade may need a compatible cooler or firmware update. Confirm the exact models in manufacturer documentation.

Step 05

Compare the cost of paths

Add the cost of supporting parts to the headline upgrade. If several old components must change at once, compare that total with a new platform or a complete system.
