What Makes a Great Gaming Desktop
CPU (the “brain”)
- 6–8 cores for esports and 1080p high FPS.
- Strong 8 cores for 1440p and all-round gaming.
- 8–12 cores for 4K, streaming, and content creation.
- Prefer high boost clocks and large cache for competitive titles.
GPU (the “engine”)
- 1080p High/Ultra: mainstream, efficient GPUs.
- 1440p High/Ultra: step up to mid-high GPUs.
- 4K Ultra: flagship cards, DLSS/FSR recommended for ray tracing.
RAM & Storage
- 16 GB is the baseline; 32 GB if streaming, editing, or modding.
- 1 TB NVMe minimum; add 2 TB if rotating many AAA titles.
- Keep an extra M.2 slot free for future growth.
Cooling & Airflow
- Quality air coolers work well for most builds.
- 240–360 mm AIOs help with high-end CPUs or compact cases.
- Mesh-front cases and clean cable routing keep temps and noise low.
