- HDD (1TB–2TB): For bulk storage of less frequently played titles, media, or backups.
The best setups combine both, giving you speed without sacrificing space.
Motherboard: The Backbone of Compatibility
If your CPU is the brain and your GPU the soul, the motherboard is the nervous system. Every component talks through it, which makes choosing the right one absolutely critical.
Chipsets and Future-Proofing
Think of the chipset as the “language” your motherboard speaks. Choose the wrong one, and your dream CPU or GPU may never work together.
- Entry-Level: B-series motherboards are affordable and perfect for budget builds.
- Mid-Range: X-series chipsets give better overclocking and support for higher-end CPUs.
- High-End: Z-series or X670 boards are for enthusiasts who demand full performance.
Future-proofing is key. Investing in a motherboard that supports the latest standards—PCIe 5.0, DDR5, USB-C—means your system won’t feel outdated in two years.
Expansion Slots and Ports Gamers Need
A great motherboard should include:
- Multiple PCIe slots for GPUs or capture cards.
