Some UK-Buying Tips & What to Avoid
- If buying prebuilt from UK retailers (or shops shipping to UK), check the CPU launch date and model — avoid very old CPUs or unknown “economy” chips with vague specs.
- Prioritise SSD storage over HDD or slow drives — the speed difference affects boot time and overall responsiveness.
- For most users: aim for 16 GB RAM as a baseline; choose 32 GB+ if you do editing / creative work or want longer-term smoothness.
- Try to get a PC with a modern CPU + upgrade-friendly motherboard / PSU if you want ability to upgrade down the line.
Key PC components and what to look for
Here are the main parts you should check — they determine performance, responsiveness, and usefulness of your PC.
| Component | What to check / Why it matters |
|---|---|
| CPU (Processor) | The “brain” of your PC. Look at model (e.g. Intel i5/i7, AMD Ryzen 5/7), number of cores/threads, clock speed. For anything besides basic tasks, a modern mid-range or better CPU is recommended. |
| RAM (Memory) | Allows your PC to run multiple tasks smoothly. For simple tasks, 8 GB can suffice. For heavier tasks, multitasking or gaming — aim for 16 GB or more. For editing, 3D work or future-proofing, 32 GB+ is ideal. |
| Storage (SSD vs HDD) | SSDs (especially M.2 NVMe) offer much faster boot and load times than older HDDs or SATA SSDs. If you can, get an SSD for OS and apps. If you need lots of storage for media/files, 1TB+ is a good sweet spot. |
| GPU (Graphics Card) / Integrated Graphics | If you only do office tasks or browsing — built-in graphics is fine. For gaming, video editing, design, 3D, etc. — you’ll want a dedicated GPU. |
| Ports / Extensibility / Upgrade Path | Make sure the PC has enough ports (USB, HDMI/DisplayPort, etc.) for your peripherals. If you plan to upgrade later (RAM, GPU, drives), make sure the motherboard and PSU allow it. |
Also — avoid desktops with very low specs (e.g. 4 GB RAM, very old CPUs, weak integrated graphics) unless you know you only need them for basic tasks
