Buyer's Guide

Making smart choices when buying a custom PC isn't just about specs — it's about matching hardware to your workload, your budget, and your timeline.

Define Your Workload First

Before choosing any component, answer one question: what will this computer spend most of its time doing? Gaming prioritizes fast single-core CPU speed and GPU power. Video editing needs fast storage and CPU core count. 3D rendering is GPU-heavy. Virtualization needs cores, RAM, and fast storage. Defining this upfront prevents overspending on the wrong things.

Budget Allocation

A common mistake is spending too much on the CPU and too little on the GPU (for gaming), or vice versa. As a rule of thumb for gaming machines: allocate 35-40% of your budget to the GPU, 15-20% to the CPU, 10% to RAM, 10% to storage, and the remainder to the platform (case, PSU, cooling, motherboard). For workstations, shift more toward CPU and RAM.

Don't Skimp on the PSU

The power supply is the one component that touches everything else. A failed or inadequate PSU can damage other components. Buy 80+ Gold or better, plan for 20% headroom above your expected load, and stick to known brands. A $50 PSU in a $3000 build is a false economy.

Platform Longevity

Consider how long you want this platform to last. Intel LGA1700 is end-of-life. AMD AM5 will receive CPU updates for years. HEDT platforms (Threadripper, EPYC) are expensive but offer more PCIe lanes and memory channels than any mainstream platform.

The StealthMachines Approach

We've been building custom PCs since 2004. Our configurator walks you through every component decision in order of dependency — from platform choice through warranty selection. Every part is priced from current supplier listings, updated weekly. Call us at 888.273.2440 if you want help choosing.
