Desktop PC Buying Guide


Delve into the world of desktop PCs and find a computer that'll meet your needs.

Determine Your Desktop PC Needs


Determine Your Desktop PC Needs

Four simple steps will turn you into a savvy desktop PC shopper:

  1. Nail down your equipment needs: Do you need a box or a complete system? If you only want to upgrade your computer, buy a box in PC tower or desktop form. If you need a monitor (traditional CRT or flat-panel LCD), speakers, keyboard, and mouse, buy a complete system. Some sellers will also include a printer, scanner, or memory card reader. All-in-one systems that integrate computer hardware, including drives, into the monitor are also available.

  2. Decide if you need a brand name desktop: Buying a computer from a well-known company like Dell, Sony, HP, or Gateway can give you piece of mind because you know the company's name and reputation. However, desktop PC custom/whitebox computers cost less and have comparable hardware and system configurations.

  3. Determine how you want to use your desktop: People who only want to work in Microsoft Office applications have drastically different computing needs than people who want to play 3D games or edit video. Before you start to shop, consider how you plan to use your computer. It should meet your personal needs as well as the system requirements set by your Internet Service Provider.

  4. Discover the desktop of your dreams: Once you know what you want, use eBay's Product Finders and keywords to narrow down item listings.

Explore Common Desktop PC Components


Explore Common Desktop PC Components

Desktop computers are only as good as the parts that come inside them. When looking at these parts, also called components, know that:     

  • 1GB equals 1024MB.

  • 1GHz is faster than 1MHz.     

  • Faster processors offer faster performance.    

  • As you increase RAM, program performance improves.    

  • You can store more files on larger hard drives.

Compare desktop PC processors

The processor is your computer's nerve center. Sellers provide information about the type of processor a computer contains and its speed in megahertz (MHz) or gigahertz (GHz). When you shop, here's how to compare them.    

  • Processor speed: 1GHz processors are faster than 1MHz processors. Faster processors offer better system performance and usually cost more than slower processors.

  • Intel & AMD: Intel and AMD use different speed naming conventions for their processors. Intel uses processor speed while AMD compares its CPUs to their Intel counterparts. When you see a 2.8 GHz Pentium processor, know that it's comparable to an AMD 2800+ processor. Higher numbers offer better performance.     

  • Celeron & Pentium: Intel makes two lines of processors: Celeron and Pentium. Celeron is an inexpensive, no-frills alternative to Pentium processors. You trade off some speed for a lower price.     

  • Hyperthreading (HT): Hyperthreading (HT), an Intel technology, lets processors in the 3GHz and faster range work on two separate threads of data at the same time. Your software needs to be optimized for hyperthreading in order to see improved performance. More software will support the technology in the next few years.     

  • Dual processors: Some computers contain two processors that can take turns working with data. You will only see improved performance if the software you run is optimized for dual processing.

Make sure you have enough memory (RAM)

Random Access Memory (RAM) stores data in a temporary holding area so that your desktop doesn't have to access slower hard drive memory when programs request information. Programs, including operating systems, need a certain amount of RAM to run, with more RAM providing better performance. For example, Windows XP requires at least 128MB RAM to run according to Microsoft. Most people find the number closer to 256MB and see even better performance with 512MB RAM, 1GB RAM, or more.

Select your hard drive capacity

A computer's hard drive stores all your programs and files. A drive with a higher storage capacity (measured in GB) lets you save more data than a drive with a lower storage capacity. You only need 20GB to 40GB of hard drive space if you only plan to store your operating system, programs, documents, and a few photos. You'll want at least 80GB if you plan to save a lot of large files such as high-resolution images, movies, or your entire music collection. Additional external hard drives also work well for data backup purposes and for storing large files.

Back up with a CD or DVD burner

CD and DVD burners allow you to back up your data, create your own music CDs, or burn your home videos to DVD.

  • CD-R: Write to CD-R media and create your own audio CDs. You can only burn and finalize a CD-R once.

  • CD-RW: Back up your data to a re-writable CD-RW.     

  • DVD+RW/-RW: A DVD can hold more data than a CD, making it a great backup data storage option. A combination DVD+RW/-RW burner can write to the popular DVD+RW and DVD-RW media formats.    

  • Combo Drives: Combo drives can read or write to two media formats. They may also include a read-only media format such as CD-ROM (to read CDs) or DVD-ROM (to play DVD movies and read CD-RWs).

Connect to your network

In order to connect to a home network or broadband Internet service, you'll need a 10/100 Network Interface Card (NIC), which comes standard on many PCs. If you want to set up a wired or wireless home network, read eBay's Networking Buying Guide.

Interact with your favourite gadgets

Digital cameras, MP3 players such as the iPod, video cameras, and other gadgets transfer data to and from your computer over a high-speed USB 2.0 or FireWire (also called IEEE 1394) connection. Many also work over slower USB 1.1 connections.

Get great graphics and sound

Gamers and multimedia enthusiasts will want one of the latest video cards and sound cards. They process video and audio, freeing up memory for other system tasks. You may also need separate cards if you buy an older PC that does not have a motherboard with onboard sound and video processing.

Notes on upgrading: Desktop owners can easily replace older components or install new components to improve performance and add functionality. For example:   

If you plan to upgrade components, ask the seller to provide you with a manual for the desktop. The manual specifies which hardware the computer's motherboard supports.

Choose Your Version of Windows


Choose Your Version of Windows

Microsoft currently offers three versions of its Windows operating system for home and home office use:

  • Windows XP Home: Windows XP Home has a clean and simple interface that works well for most home users and offers more stability than previous versions of the Windows operating system.

  • Windows XP Media Center Edition: If you want to connect your computer to your TV, or use the computer as a media hub, buy a Media Center PC running Windows XP Media Center Edition.     

  • Windows XP Professional: Designed for business users, Windows XP Professional provides extra support for networking. It also includes a Remote Desktop feature that allows you to access the computer over the Internet.

You will also find computers that run older versions of Windows on eBay, including Windows 95, 98, ME, and 2000.
