Buying Guide: What to Look For in a Desktop PC in 2026
Buying a desktop in 2026 is genuinely easier than it was a few years ago, but there are still traps to avoid. Here's what actually matters.
CPU: Generation matters more than clock speed. A newer processor at 3.5GHz will often outperform an older chip at 5.0GHz. Look for Ryzen 5000 series or newer on the AMD side, and 12th-gen Intel or newer on the Intel side. Anything older than that is starting to show its age in 2026.
GPU: This is the big one for gaming. If gaming is any part of your plans, you need a dedicated GPU. Integrated graphics (like the Vega 8 in the Vibox I-7) are fine for everyday tasks but won't run modern games properly. For 1080p gaming, the RTX 5060 is a solid starting point. For 1440p, look at the RTX 5060 Ti or above. For 4K, you're into RTX 5070 Ti and RTX 5080 territory.
RAM: 16GB is the minimum in 2026. 8GB machines still exist, and they're not worth buying. 16GB handles everyday tasks, gaming, and light multitasking comfortably. If you plan to stream, edit video, or run multiple demanding applications at once, 32GB is worth the extra spend.
Storage: NVMe SSD only. Avoid any machine with a traditional HDD as the primary drive. SATA SSDs are acceptable but slower than NVMe. For storage capacity, 1TB is fine for most users. If you have a large game library or work with large files, 2TB is worth considering.
PSU: Don't overlook this. A cheap, unrated power supply is a reliability risk. Look for 80+ rated PSUs. For RTX 5060 builds, 650W is adequate. For RTX 5080 and above, you want 850W or more.
Price brackets to know: Under £500 gets you a capable everyday PC with integrated graphics. £700 to £1,000 gets you into genuine 1080p gaming territory. £1,000 to £1,500 covers solid 1440p gaming. Above £1,500, you're in 4K and high-refresh-rate territory.
Common mistakes: Buying on clock speed alone, ignoring PSU quality, choosing a machine with only 8GB RAM, and paying premium prices for outdated GPU generations. Always check the GPU model carefully. An RTX 3060 and an RTX 5060 sound similar but are very different cards.
