What Is Worth Spending Money On, and What Is Not

Computer buying advice mostly compares specifications. The more useful question is where an extra hundred changes your daily experience, and where it buys a number you will never notice.

Worth spending on

Storage — capacity and type

Solid state, always. The difference against a mechanical drive is felt every time you use the machine. Never buy a new computer with a mechanical system drive.

Enough capacity. Running out is genuinely disruptive, and a drive kept near full performs worse. Buy more than you think, because it is difficult to add later in a laptop and irritating in a desktop.

The premium for the very fastest drives is not felt in ordinary use. The gap between mechanical and solid state is enormous; the gap between good and excellent solid state is not.

Memory, up to the point you need

16 GB is the sensible floor for a machine you want to keep. Beyond what you use, it does nothing.

In a laptop, this is a one-time decision if the memory is soldered. Buy for the machine's life, not for today. See RAM explained.

The screen

The thing you look at for every hour of use, and where people underspend consistently.

Resolution and size matter more than refresh rate for ordinary work. A larger, higher-resolution screen changes how much you can see and how long you can work comfortably.

On a laptop, screen quality varies enormously at the same price, and it is rarely on the comparison list.

An external monitor transforms a modest laptop at a desk, and it outlives several machines.

The keyboard and mouse

You touch them constantly, they cost little, and they last a decade.

On a desktop, spend properly — a good keyboard is a small fraction of the machine and it improves every hour.

On a laptop, try it if you can. Keyboards vary and you cannot change it.

The power supply, in a desktop

Not the cheapest. It is the component whose failure can damage others, and a poor one delivers less than its label claims. See computer hardware.

A chair and desk height

Not a computer component and it affects your experience more than most of them. See ergonomics in computing.

Longer support

A device with more years of updates is worth more, and almost nobody compares this. See when a device stops receiving updates.

Not worth spending on

Processor beyond your actual use

For browsing, documents, video and light work, the difference between a mid-range processor and a top one is imperceptible.

It matters for sustained demanding work — video encoding, rendering, compilation, simulation, and processor-heavy games.

If you do not know whether you need it, you do not.

Graphics beyond your actual use

Same logic, more expensive. A powerful card is necessary for demanding games and heavy creative work and does nothing for ordinary use.

And it must be matched — a high-end card with an older processor is limited by the processor.

The fastest memory

Capacity matters; speed rarely does at ordinary use.

Extended warranties

Frequently poor value, and they overlap with statutory rights that already exist in many countries. Check what you are already entitled to before buying more.

Sometimes worth it for laptops used in demanding circumstances, particularly accidental damage cover, which statutory rights do not provide.

Preinstalled software bundles

Trials that expire and nag. Usually the first thing to remove.

"Gaming" branding on peripherals

Frequently a price premium for lighting and marketing. Some of it is genuinely better; the branding is not the indicator.

Cable and accessory markups

A cable meeting the specification works. The premium for expensive digital cables buys nothing measurable — the signal either arrives or does not.

With one caveat: the specification does matter. A cable rated for an older standard can silently limit a newer monitor. Buy the right specification, not the expensive one.

The judgement calls

Screen refresh rate — transformative for fast games, mildly nicer for everything else.

A larger drive against an external one — internal is faster and neater; external is portable and moves to the next machine.

Buying used or refurbished — frequently the best value in the whole category, particularly ex-business laptops. Check battery and drive health. See laptop or desktop.

Buying now against waiting — there is always something better coming. Buy when you need it, from the current generation.

Where people consistently get it wrong

Spending on the processor and economising on the drive. Backwards for almost everyone.

Buying a laptop with 8 GB of soldered memory because it was cheaper, then finding it inadequate two years later.

Ignoring the screen while comparing processors.

Buying peripherals as an afterthought when they outlive the machine.

Buying more machine than needed because the specification comparison encouraged it — and then replacing it on the same cycle anyway.

Buying too little machine to save money now, then replacing sooner. The cheapest machine is frequently not the cheapest over five years.

A simple allocation

For a typical budget, roughly.

Storage: solid state, generous capacity. Non-negotiable.

Memory: 16 GB, more if you know you need it.

Processor: mid-range unless you have a specific demanding use.

Graphics: integrated unless you have a specific need.

Screen: as good as the budget allows after the above.

Peripherals: properly, once, and keep them.

Then check the support period before committing.

The short version

Storage type and capacity, enough memory, and the screen are where money changes your daily experience.

Processor and graphics beyond your actual use buy numbers you will not notice.

Peripherals outlive machines — buy well once.

Check the support period, which nobody compares and which determines how long the device is usable.

And spending on the processor while economising on the drive is the most common mistake in this whole area.
