Guides is where computingskill.com/ answers the bigger, "how do I actually do this" questions — as opposed to the single-purpose reference pages in Hardware or the number-crunching in Calculators. Each guide walks through a specific decision or process end to end: how much RAM you really need for gaming versus productivity, how to pick a gaming GPU without overspending, how to size a PSU correctly, how to plan and execute a PC upgrade, and how to actually improve FPS once you know where the problem is.
This section also includes two “bottleneck explained” guides that dig into what CPU and GPU bottlenecks actually are, why they happen, and how to spot one in your own system before you spend money fixing the wrong part. Alongside those are head-to-head comparison guides — SSD vs HDD, NVMe vs SATA, DDR4 vs DDR5, and 1080p vs 1440p vs 4K — that lay out the real differences between two options people are commonly choosing between.
These guides pair naturally with the calculators and hardware pages elsewhere on the site: a guide will tell you how to think about a decision, while a calculator or hardware page gives you the specific number or spec detail to apply that thinking to your own parts. The four comparison guides listed here also appear on the dedicated Comparisons hub, since they double as straightforward “which one should I pick” references as well as full guides — that overlap is intentional, not a mistake.
Frequently Asked Questions
What's the difference between a Guide and a Hardware page?
Hardware pages are focused reference material on a single component — what it is, what its specs mean. Guides are broader and more decision-oriented, walking through a process (like upgrading a PC) or a comparison (like DDR4 vs DDR5) rather than covering one part in isolation.
Should I read a guide before or after using a calculator?
Either order works, but if you’re new to a topic, reading the relevant guide first usually makes the calculator’s output easier to interpret, since the guide explains the concepts the calculator is estimating.
Why do some comparison guides also appear on the Comparisons hub?
Pages like SSD vs HDD or DDR4 vs DDR5 work as both an in-depth guide and a quick reference comparison, so we link them from both sections rather than force you to remember which hub they “belong” to.
Are the bottleneck guides the same as the Bottleneck Calculator?
No. CPU Bottleneck Explained and GPU Bottleneck Explained are written explanations of what a bottleneck is and how to recognize one. The PC Bottleneck Calculator is an interactive tool that estimates whether a specific CPU/GPU pairing you enter is likely to be bottlenecked.
