Most people buy a laptop the wrong way round. They pick a processor, work down the spec sheet, and end up paying for performance they will never touch while running out of memory on the school run of browser tabs.
Here is how to work out what you actually need, and just as usefully, where spending more stops doing anything for you.
Start with what you do, not with the specs
Be honest about your actual day. Not what you might do one day, what you do most weeks.
Browsing, email, documents, streaming, video calls. This is most people, and it needs far less machine than the shop will sell you.
Office work with a lot open at once. Many tabs, spreadsheets, a video call running alongside everything else. Still not demanding on the processor, but demanding on memory.
Photo editing, light video, design work. Now the processor and memory both matter, and storage speed starts to count.
Gaming, 3D, CAD, heavy video. This is the only group that genuinely needs dedicated graphics and a fast processor.
Everything else is somewhere between one and two. If you fall there, buy for memory and an SSD, not for the processor.
What actually makes a laptop feel fast?
Not the processor. This is the single most common mistake.
An SSD is the biggest difference by far. If a machine still has a mechanical hard drive, that is why it feels slow, and swapping it is the cheapest transformation available. Boot goes from minutes to seconds. Every laptop we would recommend has an SSD already.
Then memory. Running out of memory is what makes a machine stutter when you have things open. It is the second most common cause of a laptop feeling slow.
Then the processor, and for most people it is a distant third. A modern entry-level processor handles browsing, documents and video calls without breaking a sweat.
Spend in that order and you will be happy. Spend processor first and you will have a fast machine that still stutters with fifteen tabs open.
How much memory do I need?
8GB is the practical floor. It works for browsing, documents and general use. It will feel tight if you keep a lot open.
16GB is the sweet spot for most people and what we would suggest if the budget allows. It is the difference between a machine that copes and one that never makes you think about it.
32GB if you edit video, run virtual machines, work with large datasets or do serious 3D. Below that it becomes the bottleneck.
Two things to check before you rely on upgrading later. Many thin laptops have memory soldered to the board with no slots at all, so what you buy is what you get forever. And memory prices are unusually high at the moment because supply has been diverted toward AI data centres, so upgrading later may cost more than it would have to buy it fitted.
What processor do I actually need?
For most people, far less than they buy.
Entry level, Intel Core i3 or Core 3, AMD Ryzen 3, or the older Celeron and Pentium parts. Fine for browsing, documents and streaming. Genuinely adequate for a lot of people.
Mid range, Core i5, Core 5 or Ryzen 5. The sensible default. Handles everything most people do with headroom to spare, and it is where the value sits.
High end, Core i7, Core 7, Ryzen 7 and above. Worth it if you edit video, compile code, run simulations or do anything that keeps the processor busy for minutes at a time. Not worth it for browsing, no matter what the shop says.
One thing worth knowing. A newer generation mid-range processor usually beats an older generation high-end one, and costs less. Generation matters more than the tier.
Do I need dedicated graphics?
Probably not.
You need it if you game, do 3D or CAD, edit video seriously, or run anything that specifically asks for a graphics card.
You do not need it for browsing, office work, streaming, photo editing, or video calls. Modern integrated graphics handle all of that comfortably and even drive external monitors fine.
Dedicated graphics adds cost, weight, heat and shortens battery life. If you do not need it, you are paying three times over.
How much storage?
256GB is workable if you keep files in the cloud and do not install much. It fills up faster than people expect.
512GB is the comfortable default and what most people should buy.
1TB or more if you keep photo libraries, video, games or large project files locally.
Storage is one of the easier things to add later on most machines, and an external drive covers bulk files cheaply, so this is a reasonable place to economise if the budget is tight.
What about the screen?
Underrated, because you look at it constantly.
Resolution. Full HD, 1920x1080, is the sensible minimum and fine for most work. Higher resolutions look sharper but cost battery life. If you are choosing between a better processor and a better screen, the screen is often the one you will notice daily.
Matte or glossy. Matte is easier to live with under office lighting or near a window. Glossy looks punchier in a shop.
Brightness matters more than people realise, particularly if you work near windows or outside.
And size is a real decision. 13 and 14 inch machines are easier to carry. 15.6 and 16 inch give you more to work with on a desk. If it lives at a desk, buy bigger. If it travels, buy smaller and use an external monitor at home.
Where should you stop spending?
Some honest advice on where the money stops working.
Do not buy a high-end processor for office work. You will never see the difference. Put that money into memory and a better screen.
Do not buy dedicated graphics you will not use. It costs battery life and weight for nothing.
Do not buy 4K on a 14 inch laptop unless you specifically need it. You will burn battery on pixels you cannot resolve at that size.
Do not buy 8GB on a machine with soldered memory if you can stretch to 16. That is the one decision you genuinely cannot undo.
The sensible default
If you want one answer rather than a decision tree, this covers most people well:
A mid-range processor, 16GB of memory, a 512GB SSD, and a Full HD matte screen, in a business-class machine if you can. That handles everything short of gaming and heavy creative work, and it will still feel fine in four years.
If the budget is tight, drop the storage to 256GB before you drop the memory to 8GB. You can add storage later. On many machines you cannot add memory at all.
Does used change the answer?
It improves it, considerably.
The same money buys substantially more machine second-hand, and business-class used machines are the sweet spot because they were built to last and are still repairable. A three or four year old business laptop with 16GB and an SSD outperforms a new budget machine at the same price, usually by a wide margin, with a better screen and keyboard as well.
The things to check are battery health, cosmetic condition and whether parts are still available, which is exactly why we grade honestly and stock the parts.
Frequently Asked Questions
How much RAM do I need in a laptop? 8GB is the practical floor and 16GB is the sweet spot for most people. Go to 32GB only if you edit video, run virtual machines or work with large datasets.
Is an i7 worth it over an i5? For browsing, documents and general use, no. It is worth it if you edit video, compile code or run software that keeps the processor busy for minutes at a time.
Do I need a dedicated graphics card? Only for gaming, 3D, CAD or serious video editing. For everything else integrated graphics is fine and costs you less weight, heat and battery life.
What makes a laptop feel fast? An SSD first, then enough memory, then the processor. Most people overbuy processor and underbuy memory, which is why their machine still stutters.
Is a used laptop a good idea? Often yes. The same money buys considerably more machine, and used business laptops in particular were built to last and remain repairable years later.
