PC Guides: Your Complete Hub to Build, Upgrade, and Buy a PC

Welcome to our PC guides hub, your starting point for everything about building, balancing, upgrading, and buying a PC. Whether you are planning your first build, chasing more frames, or just trying to understand your computer, we have a clear, plain-English guide for it.

This page points you to the right place fast. Pick the area you need below, and dive in. No jargon, no hype, just honest help.

Start With Our Free Tools

The fastest way to answer a real question about your PC is to use one of our free tools. They need no sign up and work on any device.

Our bottleneck calculator is the heart of the site. Enter your processor and graphics card and it tells you in seconds whether they are balanced or if one part is holding the other back. From there, our FPS calculator estimates the frame rates your build will reach in real games, the PSU calculator sizes the right power supply for your parts, and the PC compatibility checker confirms everything fits and works together before you buy. Not sure what is inside your machine? Our guide on how to check your PC specs shows you how.

Understanding Bottlenecks

A bottleneck is when one part holds the rest of your PC back, and understanding it saves you from wasting money. Start with our guide on what is a bottleneck, then learn what counts as normal with acceptable bottleneck percentage. To find your own, see how to check your PC bottleneck.

For checking specific pairings, we have dedicated tools: the CPU and GPU bottleneck calculator for the classic pairing, plus the CPU bottleneck calculator, the GPU bottleneck calculator, and the RAM bottleneck calculator for each part on its own.

Processors (CPUs)

The processor is your PC’s brain. If you are choosing or learning about one, start with what is a CPU, then our CPU buying guide for how to pick the right one.

For recommendations, see the best CPUs overall, the best CPU for gaming, the best budget CPU, and the best CPU for work, editing, and streaming. To compare chips, use our CPU comparison guide and the CPU benchmarks hierarchy. By brand, we cover AMD Ryzen CPUs and Intel Core CPUs. Already have a chip? See our CPU upgrade guide, and if yours runs hot or maxes out, our high CPU usage fix guide helps.

Graphics Cards (GPUs)

The graphics card drives your frame rate, so it is the most important part for gaming. Begin with what is a GPU, then our GPU buying guide.

For picks, see the best GPUs overall, the best GPU for gaming, and the best budget GPU. Compare cards with our GPU comparison guide and the GPU benchmarks hierarchy. By brand, we cover NVIDIA GeForce GPUs and AMD Radeon GPUs. When it is time to upgrade, our GPU upgrade guide walks you through it.

Memory (RAM)

Memory is easy to get right once you know the rules. Our guide on how much RAM you need answers the most common question, our RAM buying guide covers speed and type, and the best RAM for gaming names the sweet spot.

Building a PC

Building your own PC saves money and is easier than it looks. Start with PC parts explained to learn each component, then follow our step-by-step how to build a PC guide.

For complete parts lists, see our gaming PC build guides by resolution, our budget PC builds by price, our flagship high-end PC builds, and our streaming PC build for creators.

Buying a PC

Prefer to buy ready-made? Our PC buying guide shows how to choose a prebuilt, and our gaming PC price guide explains what things should cost.

For specific picks, see our cheap gaming PC options or, for second-hand value, our used gaming PC guide. To shop, our where to buy a gaming PC guide covers online retailers, and our computer stores near me guide covers buying in person.

Performance and Optimization

Already have a PC and want more from it? Our PC optimization for gaming guide covers free ways to boost frames, and our PC software, drivers, and maintenance guide keeps your machine healthy. To measure your results, see how to benchmark your gaming PC, and for your screen, our gaming monitor guide explains refresh rate and resolution.

Choosing a Form Factor

PCs come in different shapes for different needs. Our desktop computer guide compares towers and all-in-ones, our gaming laptop guide covers portable gaming, and our mini PC guide explains small form factor builds for tight spaces.

How to Use These PC Guides

Not sure where to start? A simple path works for most people:

• Planning a build or buy: start with the bottleneck calculator and FPS calculator to set a balanced target, then read the relevant build or buying guide.
• Upgrading: check which part is your limiter first with the bottleneck calculator, then read that part’s upgrade guide so you spend where it counts.
• Just learning: begin with the “what is” guides for the CPU, GPU, and bottlenecks, then explore from there.

The golden rule across every guide is balance: match your parts to each other and to the resolution you play at, and you get the best performance for your money.

Frequently Asked Questions

Where should I start with PC guides?

Start with our free bottleneck calculator to check if your parts are balanced, then read the guide that matches your goal, whether that is building, buying, or upgrading. The “what is” guides are best if you are new to PC hardware.

Do I need to build my own PC?

No. Building saves money and teaches you how your PC works, but buying a prebuilt is easier and comes with a warranty. Our building and buying guides cover both paths so you can choose what suits you.

How do I know what to upgrade?

Use our bottleneck calculator to find your limiter, the part holding the rest back. Then read that part’s upgrade guide. This way you spend money where it gives the biggest performance gain.

Are these PC guides free?

Yes, every guide and tool on the site is completely free, with no sign up needed. We aim to give honest, plain-English help for building, balancing, upgrading, and buying a PC.

What is the most important part of a gaming PC?

The graphics card drives your frame rate, so it matters most for gaming and should get the largest share of your budget. Keep it balanced with a suitable processor, which our bottleneck calculator helps you check.
