Buy for what you do—not for the biggest numbers on the box. Start with your programs, budget, and where you will use the computer.

Our everyday starting point is 8GB of memory and 256GB of SSD storage. Choose 16GB of memory or 512GB of storage if you need more. These are PC Ninja’s buying tips, not requirements for every person or program.

GB means gigabyte; TB means terabyte. They measure memory or storage space. About 1,000GB equals 1TB.

Start with the way your household will use the computer, then choose the form that fits.

Five labels worth understanding

Processor (CPU)

CPU means central processing unit. This chip runs your programs. See the simple processor choices below. [2]

Memory (RAM)

RAM means random-access memory. It gives open programs room to work; it does not store your photos. [1] Our starting point is 8GB; choose 16GB when you regularly use more programs at once.

Storage (SSD)

SSD means solid-state drive. It holds programs and files, and is faster than an older hard drive. [3] Start with 256GB; consider 512GB for more files or 1TB for a large collection.

More help: SSDs versus older hard drives and how much a 1TB drive holds.

Graphics (GPU)

GPU means graphics processing unit. It handles images and video. Built-in graphics suit lighter tasks; demanding games or editing may need stronger graphics. [4] Check your program’s requirements.

Cooling

Keeps parts from getting too hot. Look at reviews for heat and fan noise, especially if you play games or edit video for long periods.

PC vs. Mac: which should you choose?

PC means a Windows computer in this guide. A Mac is an Apple computer running macOS.

  • Our PC advice: start here when school or work requires Windows, or computer games are a priority.
  • Our Mac advice: consider one if your programs work on it and you like its links with an iPhone or iPad. Apple offers sharing features on supported devices. [8]
  • For either: check the complete price and whether you can add memory or storage later. Some Mac mini models cannot have more memory added. [13]

What about Linux?

Linux is another choice for the computer’s main software. It works on supported PCs and some Macs—check the exact model first. [11] [12] This guide keeps the focus on Windows and macOS.

Will your programs and printer work?

Ask your school, employer, or software maker before buying. Some Windows computers have extra limits on games, programs, and older devices. [9] For a Chromebook, also check your school’s rules.

For a new Windows PC, look for Windows 11. Regular Windows 10 support ended October 14, 2025; extra security updates have separate eligibility and enrollment rules. [10] See our Windows 10 support guide.

Laptop, desktop, or something smaller?

  • Laptop: choose one if you need to carry it around. Check its weight, keyboard, screen, and battery reviews.
  • Desktop tower: consider one for a fixed desk. Ask which parts can be replaced or improved later.
  • All-in-one: the computer is built into the screen for a tidier desk. Check repair options before buying.
  • Mini-PC: a small computer that uses a separate screen. Check that it connects to the devices you own.

Small size does not tell you whether it can handle your games or editing programs. Check the exact model.

Match the computer to the household

Schoolwork

Check the school’s rules first. A laptop is handy for carrying to class. Consider 16GB memory and 512GB storage for more room to work.

Everyday home use

For email, shopping, documents, and video calls, start by comparing computers with 8GB memory and 256GB SSD storage.

Photo, video, or demanding work

Check your programs’ recommendations. Consider 32GB memory for large projects, plus enough storage for your files.

Games

Consider 16GB memory and 512GB or 1TB storage. Check the graphics needed for your favorite games before paying for a “gaming” label.

These are our starting points, not performance guarantees. Your programs may need more—or less.

Which processor should you look for?

The processor (CPU) is the part of your computer that runs programs and carries out instructions. [2]

Intel Core and AMD Ryzen are names you will see while shopping. [5] [6] Here is our simple starting point—not a promise about every model.

  • Basic tasks on a tight budget

    Compare a recent Intel Core 3, Core i3, or AMD Ryzen 3 for email and simple documents.

  • Everyday use and schoolwork

    Start with Intel Core 5, Core Ultra 5, a recent Core i5, or AMD Ryzen 5. These are the middle-range options we would compare first.

  • Games

    For gaming, an Intel Core 5, Core Ultra 5, a recent Core i5, or AMD Ryzen 5 is a good starting point. Check which graphics card your games recommend, and leave room in your budget for it, too.

  • Larger photo or video projects

    Compare Intel Core 7, Core Ultra 7, a recent Core i7, or AMD Ryzen 7. Only pay for a higher-end option if your work needs it.

  • Macs

    Compare Apple’s standard models first. If choosing an M-series chip, its Pro or Max versions are usually more than we would recommend for basic home tasks. [7]

Check the full model and reviews of the exact computer. A “5” or “7” alone does not tell you how well it will handle your work.

Do you need a custom-built computer?

Usually not for basic home tasks. Consider a custom desktop if you have specific gaming or editing needs, or want particular parts you can replace later.

Compare custom and ready-made options

Ask what the price includes, which parts can be changed later, and who handles repairs. Make sure cooling and power are suitable for the work. Custom does not automatically mean cheaper or longer-lasting.

PC Ninja offers custom builds or branded computers on a Call for Quote basis through home computer services.

Add up the whole cost

  • Desktop: add any screen, keyboard, mouse, camera, and cables you need.
  • Laptop: add a case or extra screen if you want one.
  • Either: include paid programs, setup help, and backup costs.

Check the return policy, warranty, and repair arrangements. Keep a separate backup of important files—our simple backup guide explains how.

Buying mistakes that are easy to avoid

  • Buying the biggest numbers: pay for what you need, not an impressive label.
  • Assuming you can add parts later: check before buying.
  • Trusting a “gaming” sticker: check your games and the exact computer.
  • Forgetting extras or backups: include them in your plan.

A few quick questions

Is 8GB memory enough?
It is our starting point for basic home use. Consider 16GB for more programs at once and check your apps’ needs.

Is a desktop better than a laptop?
Choose a laptop to carry around; consider a desktop for a fixed workspace.

Can built-in graphics play games?
Some lighter games, yes. [4] Check tests for the games you actually play.
