Key Buying Decisions
Match the platform
The CPU dictates the motherboard socket and chipset, which in turn dictates RAM type. Get this trio right first — everything else builds around it.
Right-size the power supply
Choose a reputable PSU with enough wattage and the correct connectors for your GPU, with some headroom. Skimping here risks the whole system.
Avoid bottlenecks
Balance CPU and GPU to your resolution and tasks so neither part is wasted. For storage choices, see our Storage hub.

Frequently Asked Questions
Does the motherboard affect performance?
Mostly indirectly — it sets which CPUs, RAM speeds, and features you can use, and affects stability, but it rarely changes raw speed much on its own.
How much RAM do I need?
16GB is the comfortable standard for gaming and general use; 32GB benefits heavy multitasking and content creation.
Do I need a graphics card for everyday use?
For browsing and office work, integrated graphics are fine. A dedicated GPU matters for gaming, 3D, and GPU-accelerated editing.
