Gaming PC Buying Guide / Updated September 2026

How to choose the right custom gaming PC

Built around the games you play. Not the biggest specification sheet.

A great gaming PC isn't the one with the most expensive components. It's the one that puts your budget into the performance you'll actually see.

Tell us what you play, the resolution and refresh rate of your monitor, and what else you want the PC to do. Everything else follows from there.

Start here

Before you choose a graphics card, answer three questions.

01

What do you play?

Competitive games, huge open worlds, simulation games and heavily modded titles can all place very different demands on a PC.

The specification should follow the games.

Different games want different things

02

What does your monitor need?

1080p, 1440p, ultrawide and 4K displays require very different levels of graphics performance.

Refresh rate matters too.

How your monitor sets the target

03

What else do you do?

Streaming, content creation, VR, Unreal Engine, school, university, work or local AI can all change where it makes sense to spend the budget.

Why the rest of your week matters

You don't need to become a PC hardware expert.

That's our job.

What matters

What actually makes a gaming PC fast?

Every component has a job. They don't all deserve the same amount of your budget.

Spend where you'll see it.

Priority: Critical

Start with the pixels.

For the majority of gaming PCs, the graphics card has the greatest direct impact on gaming performance. It draws every frame, so it decides how much detail you can turn up and how smoothly the game runs.

That's why we don't start with core counts or clock speeds. We start with what you're asking it to do: the games you play, your monitor's resolution, the frame rate you want to hold, how high you like the graphics settings, whether ray tracing matters to you, enough video memory (VRAM) for modern textures, and how long you want it to stay comfortable.

Don't ask “what's the best graphics card?” Ask what you're trying to make it do.

See how your monitor sets the target

Priority: Important

Fast enough to keep the GPU busy.

The processor prepares the work the graphics card draws: game logic, physics, AI and the instructions behind every frame. If it can't keep up, an expensive GPU sits waiting.

That matters most in CPU limited games: competitive shooters chasing very high frame rates, simulation and strategy games tracking thousands of objects, and busy multiplayer battles. A strong CPU also lifts minimum frame rates, the dips you actually notice, and leaves headroom for Discord, browsers, streaming and creative work running alongside the game.

Gaming leans on fast cores and cache far more than on huge core counts. Extra cores earn their place when you stream, edit video or render as well as play.

What we'd build today

Priority: Important

Enough RAM, without buying it for bragging rights.

16GB is a perfectly viable starting point for a focused gaming PC, and it keeps more of the budget for the graphics card. 32GB is where we'd aim for most new custom gaming PCs when the budget allows, giving the game, Discord and a browser room to breathe.

Beyond that, more memory is about what else the PC does, not frame rates.

How much memory you need

Priority: Important

Games got big.

Big modern games can take well over 100GB each, and updates keep growing. We build around fast NVMe solid state storage, which loads Windows, games and levels far quicker than older drives.

How much storage you need

Priority: Depends on the build

Cooling should match the hardware.

A cooler's job is to keep the processor and graphics card at sensible temperatures and noise levels under sustained load, so performance holds for hours rather than minutes.

The right choice depends on the processor, the case and how you want the PC to look and sound.

Air, AIO or custom loop

Priority: Invisible but critical

The component nobody should cheap out on.

The power supply feeds everything else. A good one delivers clean, stable power year after year. A poor one can cause crashes and noise, and at worst take other components with it.

We choose a quality, efficient unit with enough wattage for the hardware, room for the brief power spikes modern graphics cards produce, and headroom for a future upgrade.

Memory

16GB works. 32GB gives you room to breathe.

64GB makes sense when your gaming PC has another job too.

16GB

Gaming starting point

Enough for a focused gaming PC, particularly where keeping the budget focused on GPU performance matters most.

Best for

  • Gaming first
  • 1080p and mainstream builds
  • Getting more budget into the GPU

32GB

Gaming sweet spot

Where we'd aim for most new custom gaming PCs when the budget allows.

Best for

  • Gaming + Discord + browser
  • Modern AAA titles
  • Streaming and general multitasking
  • More breathing room for the future

64GB

Gaming + serious multitasking

More relevant when the PC also has another job.

Best for

  • Content creation alongside gaming
  • Large simulation or heavily modded workloads
  • Development, local AI and specialist applications

More RAM doesn't make your graphics card faster.

Running out of RAM absolutely makes the experience worse.

Storage

Games got big. 2TB is where we'd start.

We build on NVMe solid state storage: drives that connect directly to the motherboard and load Windows, games and levels far faster than older hard drives.

If your library outgrows it, additional storage can normally be added later.

1TB

Works, but fills quickly.

  • Windows plus a handful of big games
  • Fine for a focused library

2TB

Our practical starting point for many gamers.

  • Room for a healthy library
  • Space for updates, which keep growing
  • Fewer uninstall decisions

4TB+

Big libraries, mods, simulations and content creation.

  • Large or heavily modded libraries
  • Flight and racing sims with big add-ons
  • Recording and editing gameplay

Fast storage makes the whole PC feel faster.

It doesn't magically create more FPS.

Cooling

Air, AIO or custom loop? Cooling should match the hardware.

Air

Air cooling. Simple, dependable and excellent value.

  • Nothing to top up, nothing to leak
  • Suits a wide range of gaming builds

AIO

AIO liquid cooling. Greater cooling capacity and a different look.

  • Appropriate for many high performance builds
  • Moves heat to a radiator on the case
  • A cleaner look around the processor

Custom

Custom water cooling. Specialist cooling and visual design.

  • A hand built loop, designed as much as engineered
  • The machine as a centrepiece
  • For machines such as Renegade

We'll make sure the cooling solution matches the hardware.

You shouldn't have to calculate it yourself.

The target

Your monitor sets the target.

Before deciding how powerful your gaming PC needs to be, look at the screen it's being asked to drive.

Resolution sets how many pixels the graphics card draws in every frame. Refresh rate sets how many of those frames you'll want every second. Together, they decide how much GPU you need.

1080p

1920 × 1080

2.1M Pixels in every frame

Fast. Accessible. Brilliant for esports.

The lightest target, so more of the budget can go towards very high frame rates. For competitive players, high FPS can matter more than maximum visual detail.

1440p

2560 × 1440

3.7M Pixels in every frame

The modern gaming sweet spot.

A major improvement in image quality without the enormous graphics requirement of high refresh 4K. For most new gaming PCs, this is where we'd aim.

Ultrawide

3440 × 1440

5.0M Pixels in every frame

More pixels. More immersion. More GPU.

Particularly relevant for racing, flight simulation, expansive games and productivity. Shown at 3440 × 1440, around a third more pixels than standard 1440p.

4K

3840 × 2160

8.3M Pixels in every frame

Maximum detail. Serious graphics hardware.

Four times the pixels of 1080p in every frame. High refresh 4K gaming can demand some of the fastest graphics hardware available.

Don't buy a £3,000 PC for a £150 monitor.

Equally, don't buy an incredible high refresh 4K display and then starve it of graphics performance.

Built around what you play

Different games want different things.

Two gamers with the same budget can need quite different PCs. Here's where each type of game tends to lean.

Competitive & Esports

Fortnite, Counter-Strike, Valorant, Overwatch. Visual detail matters less than frames: high refresh monitors, very high frame rates and low latency, which leans hard on the processor.

Find PCs for your games

Priority

  1. High FPS
  2. CPU performance
  3. Low latency

AAA & Cinematic

Demanding modern games at high settings, often with ray tracing, push the graphics card harder than anything else, and high quality textures need plenty of VRAM.

Find PCs for your games

Priority

  1. GPU
  2. VRAM
  3. Visual quality

Sim Racing & Flight Simulation

Simulators calculate a lot, and often drive triple screens, ultrawides or high resolution displays alongside wheels, pedals, yokes and headsets. We plan the displays and peripherals as part of the build.

Priority

  1. CPU
  2. GPU
  3. Display configuration

Strategy & Simulation

City builders, grand strategy and colony sims can behave very differently from visually demanding AAA games. Late in a long campaign, the processor and memory often do more of the work than the graphics card.

Priority

  1. CPU
  2. Memory
  3. GPU

VR

A headset needs a high, steady frame rate for two eyes at once. Consistency matters more than peaks, and connectivity matters too, so we check the headset you use.

Priority

  1. Consistent GPU performance
  2. VRAM
  3. Connectivity

Your gaming PC probably doesn't just game.

Gaming might be the reason you're buying it, but it probably isn't the only thing it'll do.

Tell us everything you want to do with the PC.

A machine designed purely around average FPS isn't necessarily the best computer for the rest of your week.

Frequently asked questions

What is the most important component in a gaming PC?

For most games, the graphics card. It draws every frame, so it has the biggest direct effect on frame rate and visual quality.

But it only performs as well as the system around it. A processor that can't keep up, too little memory or a weak power supply can all hold an expensive GPU back. The right answer is a balanced PC, with the GPU taking the largest share of the budget.

How much should I spend on a gaming PC?

Work back from your monitor and your games rather than picking a number first. A 1080p screen for competitive games needs far less graphics performance than high refresh 4K in the latest AAA releases.

Tell us roughly what you want to spend, what you play and what you play it on, and we'll put the budget where you'll actually see it. If a smaller spend gets you everything you need, we'll tell you.

How much RAM does a gaming PC need?

16GB is enough for a focused gaming PC, particularly where keeping more of the budget for the graphics card matters most.

32GB is where we'd aim for most new custom gaming PCs when the budget allows. It gives the game, Discord, a browser and streaming room to breathe, with more headroom for the future.

64GB makes sense when the PC also has another job: content creation, large simulations, heavily modded games, development or local AI. More memory won't add frame rate on its own.

Is 1080p, 1440p or 4K better for gaming?

None is simply better. They're different targets.

1080p suits competitive players chasing very high frame rates and keeps hardware costs down. 1440p is the modern sweet spot for most people: noticeably sharper without the graphics demands of 4K. 4K gives the most detail, but high refresh 4K needs some of the fastest graphics hardware available.

The best choice is the one your PC can drive properly.

Should I choose Intel or AMD for gaming?

Both make excellent gaming processors, and the lead changes between generations.

Recently, AMD's X3D processors, with their extra on-chip cache, have been particularly strong in many games. Intel remains a strong option, especially where gaming shares the PC with creative or productivity work.

Rather than committing to a brand, we recommend whichever platform gives the best performance and value for your games and workflow when you order.

Should I choose NVIDIA or AMD graphics?

Both make very capable graphics cards.

NVIDIA GeForce RTX cards are generally stronger at ray tracing, and DLSS upscaling is widely supported. They're also the usual choice if the PC is used for creative applications or local AI, where many tools are built around NVIDIA's CUDA platform.

AMD Radeon cards often offer strong value in traditional rendering and generous video memory for the money.

We'll recommend based on your games, your monitor and anything else the PC needs to do.

Do I need liquid cooling in a gaming PC?

No. A good air cooler is simple, reliable and more than capable for many gaming builds.

AIO liquid cooling makes sense for some higher performance processors, compact cases, or where you prefer the look. Custom water cooling is a specialist choice for machines like Renegade, as much about design as temperature.

We match the cooling to the hardware so you don't have to.

Is it cheaper to build my own gaming PC?

Sometimes the parts cost a little less. But building your own also means choosing compatible components, assembling them, testing, updating firmware and drivers, and troubleshooting anything that goes wrong. Warranties are usually split across every individual part.

A Utopia PC is designed, built and tested in Kilmarnock and comes with a 10 year labour warranty and lifetime technical support. If you enjoy building, it's a great hobby. If you'd rather just play, that's our job.

How long should a gaming PC last?

A well balanced gaming PC should stay useful for years. How long it keeps up with new releases depends on your settings, your resolution and your expectations.

A quality power supply, sensible cooling and a platform with room to grow mean a graphics card or storage upgrade can extend its life, rather than needing a whole new machine.

Can I upgrade my Utopia PC later?

Yes, where it's practical. Storage and memory are usually straightforward to add, and the graphics card is the most common upgrade for gamers.

We choose power supplies and cases with sensible headroom, and we're happy to advise on the upgrade that will make the most difference when the time comes. Get in touch with your system details and we'll help.

What gaming PC do I need for Fortnite, Call of Duty, Minecraft or other games?

It depends on your monitor and the settings you want as much as on the game itself.

Fortnite and Minecraft can run on modest hardware, but high frame rates, maximum settings, shaders and big mod packs change that quickly. Recent Call of Duty releases are considerably more demanding, particularly at 1440p or 4K.

Our PCs by Game pages are a good starting point, or tell us what you play and we'll recommend the right build.

What's the difference between Core PCs and Utopia custom PCs?

Core PCs are pre-configured. We've already made the component decisions, so you choose from a focused range built around sensible specifications and value.

Our custom gaming PCs start with one of five Utopia platforms (Helix, Pandora, Rebel, Ballista or Renegade) and let you configure the performance and appearance around you.

You tell us what you want to play. We'll do the nerdy bit.

Five custom platforms. Thousands of possible specifications. 30 years of building PCs in Scotland.
