This guide will help you understand the questions to ask when shopping for a computer. It will also provide a quick reference checklist with definitions of some basic technology terms (not too many!), as well as the minimum standards we recommend for computers.
Things to Consider When Buying a Computer
1. Do You Need a New Computer?
It's possible some basic maintenance tasks or a simple hardware upgrade can boost performance and give your old computer new life. See Extending the Life of Your Computer for additional information.
2. How Will You Be Using the Computer?
If you do need a new computer, one of the most important things to consider is how you will actually use it.
A technology plan, technology budget, and technology strategy are all helpful tools to make sure you understand your current and future computing needs. See TechSoup's Technology Planning section for resources to help you plan effectively. What kind of work will your staff be doing? Basic office tasks, like creating documents and spreadsheets, checking email, and using the Internet? Or heavy-duty work with video, audio, or images? Audio-visual work tends to be resource-intensive and will require a more robust computer.
Will your staff be traveling, or only using the computer in the office?
How does the computer fit in with your existing technology?
What operating system(s) do you use? Operating systems, like Windows, use up a lot of your computer's resources. If you barely meet the minimum hardware standards for using your operating system, you may not have the computing resources to do a lot of other tasks at the same time (multitask).
What software do you use? Do you have software that only works with a certain type of computer or only runs on a particular operating system?

What are your future plans? Are you planning to upgrade your operating system or add a new kind of software? Are you planning to do different kinds of tasks in the next couple of years?
3. Mac or PC?
The choice between Mac and PC often comes down to personal preference. Both types of computers have their merits. Macs and PCs use the same kinds of internal processors, so they are equally powerful. The main difference between Macintoshes and other computers is the operating system they use: Macintosh computers run Mac OS X (the latest version is called Lion), and PCs run Windows (the latest version is Windows 7).
A few things to keep in mind:
Macintosh computers are usually more expensive off-the-shelf than a similar PC. However, some argue that the long-term cost for a PC is actually higher, due to additional software and maintenance costs.
There is some software that will only run on Windows. Make sure the software you depend on is compatible with your new computer's operating system.
The more similar your computers are, the easier your technology will be to manage. If you have different types of computers, running different operating systems, and different software, troubleshooting and maintenance become much more complicated.
Consider whether you already have a Mac- or PC-centric office and whether or not it’s worth switching some or all computers.
4. New, Used, or Refurbished?
If you plan to use the computer for basic office tasks like word processing, email, and web browsing, you probably don't need a top-of-the-line or brand new computer. A used or refurbished computer may be just fine. Used and refurbished computers are usually much less expensive than new computers. They're also a greener option, since you're extending the life of an old computer, rather than buying a brand-new one.
A refurbished computer may be a better option than a used or donated one. Refurbished computers are older machines that have been carefully inspected and updated by professionals. If you get your refurbished computer from an authorized professional refurbisher (and you always should), you will know it is in good working condition. Refurbished computers also often have a warranty of some kind. Read more about refurbished computers available to eligible organizations through TechSoup’s Refurbished Computer Initiative.
There are some additional things you need to think about when buying refurbished equipment:
Fail and return rates. Check the refurbisher's fail and return rates. Warranty. You probably won't get a three-year warranty for a refurbished computer, but a three month warranty is pretty standard. This should cover any out-of-the box problems.
Peripherals, software, and documentation. Make sure you know what is included with your computer. Refurbished computers, for example, rarely come bundled with a monitor.
If you are buying a used (rather than refurbished) computer, or accepting a donated one, make sure a knowledgeable person inspects the computer thoroughly first. This will help ensure the computer is functioning properly and that it will meet your needs. Remember that as alluring as a free or very cheap computer might seem, an old one in poor condition can actually be more trouble than it is worth. Learn more about how to buy a refurbished computer in Tips for Buying Refurbished Computers and how to avoid receiving time-wasting donated hardware in Six Tips for Accepting (and Refusing!) Donated Equipment.
5. Laptop, Desktop, or Tablet?
When deciding whether a laptop, desktop, or tablet (hand-held) computer will best meet your needs, the key things to consider are:
Price. Laptops are usually more expensive than an equally powerful desktop computer, even if you factor in the cost of a monitor for your desktop. Parts and repairs are usually more expensive for laptops as well.
Travel. If you will only be using the computer in the office, a laptop probably isn't worth the added cost.
Upgrade, repair, and maintenance. Especially if you're planning to do this yourself, keep in mind that fixing or upgrading a laptop computer is usually much more complicated than it is for a desktop computer.
Size or "form factor." Desktop computers can be the traditional bulky tower, compact models that are smaller than a loaf of bread, or an all-in-one model (where the computer and the monitor are all one piece). Laptops come in different sizes, too: from tiny netbooks with miniature keyboards and 10 inch screens to ultra-thin or ultraportable models to giant models with 17+-inch screens that don't even need a separate monitor. A few things to consider:
If you will be traveling a lot, size and weight are important considerations for laptops.
Smaller models are often more costly than a comparably equipped standard size model. There is often a trade-off between small size and computing power. Inexpensive netbooks, for example, may not be powerful enough to serve as your main computer. Tablets (as handy as they can be and as popular as they are) aren't suitable for heavy use for office productivity tasks. But they're great for web surfing, checking email, and reading documents on-the-go.
For more information, Consumer Reports has a really nice, clear discussion of the pros and cons of laptops, desktops, and tablet computers, in varying sizes. 6. Get to Know Your Technology
There are a few key things you should understand when you're making a decision about which computer to buy. We'll define them and provide the minimum standards you should be looking for to support performing basic office tasks.
|Component||Definition||Key Consideration||Minimum Standard|
CPU (Central Processing Unit)
Also known as:
This is your computer's brain, and its function – as you might imagine – is to process information.
Usually, a faster processor means a faster computer.
Performance, which is based mostly on:
Dual-core processor, with mid-range clock speed (2.6 GHz)
RAM (Random Access Memory)
Also known as:
RAM is used to temporarily store information while your computer is running. More memory allows your computer to run more quickly, up to a point.*
Confusingly, memory is not the same thing as storage(see below for additional information). Storage is what allows you to keep files and software stored long-term, while memory is what your computer uses short-term to perform its basic functions.
*32-bit operating systems can't use more than 4GB of RAM, so if you have a 32-bit OS, you don't need more than 4GB of RAM.
Amount of memory, which is measured in megabytes (MB) and gigabytes (GB). There are 1024 megabytes in a gigabyte.
Also known as:
The amount of information (files, data, software, photos, video, and so on) your computer can store.
Amount of storage, usually measured in GB.
See Hard Drive, below
Also known as:
hard disk, hard disk drive (HDD), or internal drive
The hard drive is where most of the information on your computer is stored.
There are two main types of drives:
Note: an external hard drive is basically the same thing as an internal drive. An external drive just has a case surrounding it and a cable to connect it to your computer.
Disk size: the amount of storage space on the disk.
160 GB storage capacity
How your computer connects to the Internet or networked devices.
Wired and wireless connection capability.
Also known as:
Output Ports or Interface Ports
Device ports: how your computer connects to other devices, like a keyboard, mouse, printer, digital camera, or external hard drive. Different devices use different cables to connect to different kinds of ports. The most common ports and cables are:
Audio and video ports: How your computer connects to speakers and external displays, like a monitor or television screen. There are different kinds of outputs, including:
What devices you will connect to your computer.
Device ports: Several USB 2.0 ports
Audio and Video Ports: VGA port
Also known as:
graphics processing unit (GPU)
The graphics card or chip is what allows your computer to process and display visual information (text, images, video, and basically everything you see on your computer screen).
There are two main types of graphics processors:
Amount of system memory (RAM), and tasks you are performing:
Integrated graphics: fine for most everyday office functions.
Dedicated graphics card: only needed if you're planning to work with a lot of digital media.
Also known as:
Optical drives let you read and record (or write) to CDs, DVDs, and Blu-Rays. A "burner" or "recorder," usually labeled "RW" allows you to record or write information to discs.
Most drives are labeled with the type of discs they are compatible with, as well as whether they can record or write to a disc or only play or read it.
Functioning DVD-ROM/CD-RW device
Electronic equipment connected by cable (or wireless integration) to your computer’s CPU.
For monitors, the key considerations are:
Battery and Power Consumption
When not plugged in to an outlet, laptops use a rechargeable battery for power.
Some laptops can have an extended battery added. This makes the laptop bigger and heavier, but significantly extends battery life.
Some laptops have batteries that cannot be removed, which makes them more costly to replace when the battery wears out.
Battery life: how long the battery retains power after charging.
No specific recommendation
Size or "Form Factor"
Desktops, laptops, and tablets come in different sizes.
Some desktop terms you may hear:
Unless you will be traveling a lot, size is not usually a major factor when choosing a computer.
No specific recommendation
7. Do Your Research
The following are good places to start your research:
Consumer Reports provides an easy-to-understand, comprehensive computer buying guide and product reviews. CNET and PC Magazine have more detailed technical buying guides, as well as computer reviews for laptops and desktops. Just go to their site and search for "computer buying guide," "laptop buying guide," or "desktop buying guide." Learn about 32-bit vs. 64-bit computers with TechSoup's article: Do I Need the 32-bit or the 64-bit Version?
When doing your research, keep your organization's needs, budget, and the minimum requirements in mind, and ask yourself:
Will this product meet our needs?
What do you know about the company that makes the computer? Do they have a good reputation? What about the particular computer you're looking at?
What kind of warranty do you get, and how long does it last?
How good is the company's technical support, and how long can you use it? What other hardware comes bundled with the computer? A monitor, keyboard, mouse, cables?
What software comes with the computer?
