Choosing a Gaming Motherboard
Motherboards affect overclocking, connectivity, and expandability.
Key Features to Look For:
- Chipset: X670/E (AMD) or Z790/Z890 (Intel) for overclocking and PCIe 5.0.
- VRM Quality: Stable power delivery for high CPU boost clocks.
- M.2 Slots: At least two PCIe 4.0/5.0 NVMe connectors.
- Networking: Wi-Fi 6E / Wi-Fi 7 and 2.5G / 10G LAN.
- USB-C & Thunderbolt 4 ports for peripherals.
Popular Picks:
- ASUS ROG Crosshair X670E Hero (AMD)
- Gigabyte Z890 AORUS Master (Intel)
- MSI MAG B650 Tomahawk (Budget AMD)
DDR5 RAM: Speed & Capacity
Fast memory reduces bottlenecks, especially in content creation and RAM-heavy games.
- Capacity: 32–64GB kits recommended; 16GB only for pure gaming.
- Speed: DDR5-6000 to DDR5-7200 for optimal balance.
- Latency: Lower CL values (e.g., CL30) improve responsiveness.
Storage Strategy: NVMe SSD vs SATA SSD vs HDD
- Primary Drive: 1TB+ NVMe PCIe 4.0 or 5.0 SSD (e.g., Samsung 990 Pro).
- Secondary: 2TB SATA SSD or HDD for bulk storage.
Tip: Use separate NVMe slots to enable RAID 0 for extreme throughput if your motherboard supports it.
Cooling Solutions: Air vs Liquid
High-performance parts demand efficient cooling:
- Air Cooling: Noctua NH-D15 or be quiet! Dark Rock Pro 4. Best for reliability and quiet operation.
- All-In-One (AIO) Liquid: 240mm or 360mm radiators (e.g., Corsair H150i Elite). Offers better cooling headroom.
Power Supply & Case Selection
- PSU: 80+ Gold/Platinum, 750W–1000W from Corsair, Seasonic, or EVGA.
