Gaming PC Buying Guide UK | How to Choose the Right System

Buying a gaming PC is a big decision – it's the single piece of hardware that determines how every game looks, feels and performs for years to come. This guide walks you through exactly what to look for, what matters (and what doesn't), and which WebTro systems suit different budgets and use cases. Whether you're buying your first gaming PC, upgrading from a console, or replacing an ageing rig, you'll find clear, jargon-free advice here.

How to Choose a Gaming PC

Every gaming PC is built around the same core components – but the balance between them is what determines whether a system is great value or poor value. Here's what each part actually does for your gaming experience.

CPU (Processor)

The CPU handles game logic, AI, physics and how many frames per second your CPU can "feed" to the graphics card. For most gamers, a modern AMD Ryzen 5 processor (such as the Ryzen 5 4500, 5500 or 5600) offers excellent performance without overspending. Higher-end Ryzen 7/9 chips mainly help with streaming, video editing and heavily CPU-bound games.

GPU (Graphics Card)

The graphics card is the single biggest factor in gaming performance and visual quality. As a rough guide:

  • Entry-level (GTX 1650 / RX 570 / RX 580): Solid 1080p gaming at medium-high settings in most titles, and excellent for esports games like Valorant, Fortnite and CS2.
  • Mid-range (RX 6600 / RX 6600 XT / RX 6700 XT): Strong 1080p and very capable 1440p gaming in most modern AAA titles.
  • High-end (RTX 3070 and above): Smooth 1440p and entry-level 4K gaming, plus headroom for ray tracing and high refresh-rate monitors.

RAM (Memory)

16GB of DDR4 RAM is the current sweet spot for gaming – it's enough for modern games, background apps, and Discord/streaming without slowdowns. 8GB can still work for older or less demanding titles, but 16GB is recommended for anything released in the last few years.

Storage

An SSD (solid-state drive) is essential for fast boot times, quick game loading, and snappy Windows performance. NVMe SSDs are faster still and are increasingly common even at mid-range price points. A 500GB-1TB SSD covers Windows plus a healthy library of installed games.

Cooling & Case

A well-ventilated case with good airflow keeps your components running cooler, quieter, and for longer. Cases with mesh front panels and multiple fans (often highlighted with ARGB lighting) aren't just for looks – better airflow means your CPU and GPU can sustain higher performance without thermal throttling. If you're planning to overclock or run demanding workloads for long periods, an upgraded CPU air cooler is a worthwhile addition.

Gaming PCs by Budget

Here's how WebTro's current gaming PC range breaks down by budget, so you can quickly find the right starting point for your needs.

Under £500 – Entry-Level & Esports

Ideal for esports titles (Valorant, Fortnite, CS2, Minecraft, Rocket League), general use, and 1080p gaming at medium settings.

£500-£800 – Mid-Range 1080p/1440p

The sweet spot for most gamers – smooth 1080p at high settings, and capable 1440p gaming in most titles.

£800+ – High-End 1440p & Entry 4K

For demanding AAA titles, high refresh-rate monitors, and content creation alongside gaming.

Completing Your Setup

Once you've chosen your gaming PC, a few extras can make a big difference to comfort, looks and performance:

Frequently Asked Questions

What's the difference between 1080p, 1440p and 4K gaming?

These refer to your monitor's resolution. 1080p (Full HD) is the most common and least demanding on hardware. 1440p (Quad HD) offers a noticeably sharper image and needs a mid-range or better GPU for smooth frame rates. 4K (Ultra HD) is the most demanding and typically requires a high-end GPU like an RTX 3070 or above for the best experience.

How much RAM do I need for gaming?

16GB of DDR4 RAM is the recommended minimum for modern games and is included as standard across most of WebTro's gaming PC range. 8GB can be limiting for newer titles and multitasking.

Do WebTro gaming PCs come with Windows installed?

Yes – most WebTro Gaming PCs include Windows 11 Pro or Windows 11 Home pre-installed and activated, so you can get started straight away. Check each product page for the exact specification.

Can I upgrade my gaming PC later?

Yes. WebTro gaming PCs are built using industry-standard components, so upgrades such as additional RAM, larger SSD storage, a new graphics card, or improved cooling are all straightforward later down the line.

How long does delivery take?

We offer free UK mainland delivery, with most orders arriving within 4-5 working days. Tracked (2-3 day) and Express (1-2 day) delivery options are available at checkout. See our Delivery & Returns page for full details.

What warranty do gaming PCs come with?

Which gaming PC should I choose?

As a general rule: choose an entry-level system (under £500) for esports titles and general use, a mid-range system (£500-£800) for smooth 1080p/1440p gaming in most modern titles, and a high-end system (£800+) for demanding AAA games, high refresh-rate monitors, or content creation alongside gaming.
