Choose the right PC components
Buy components for the workload and the system they will join. Start with CPU and graphics, then check the supporting parts and the complete platform cost.
The parts that shape gaming performance
CPU and graphics card
Match the processor and GPU to the games, resolution and refresh target.
Read the guide →Motherboard, RAM, SSD and cooling
Choose the features, capacity and physical arrangement the build needs.
Read the guide →CPU and graphics decisions
Use current tests of the games and settings you care about. More graphics memory is useful when the workload needs it, but capacity alone does not describe GPU speed. Similarly, a processor with more cores is not automatically the best use of a gaming budget.
Supporting parts that fit
Buy a motherboard for CPU support and useful connections. Choose a matched RAM kit, enough SSD capacity, a cooler with the correct mounting and a case that accommodates the complete installation. Check the exact generation and revision rather than trusting a familiar product family name.
Platform, power and substitutions
A CPU platform change can mean replacing the board and memory together. A graphics upgrade can need a new PSU or case arrangement. An unavailable product should be replaced by a part that satisfies the same requirements, with the consequences checked across the build.
