Desktops – Buying for Performance
If you’re looking to purchase a new desktop computer, this guide will help you make an informed decision by examining the basic components you’ll want to consider when comparing desktop systems.
CPUs and Processors
- CPUs / Processors
Comparing processors, or CPUs, has become increasingly difficult since each manufacturer has a different system for rating performance. The two main choices are Intel and AMD processors. There are detailed online resources that compare processors, but here is a quick reference guide to current recommended processors:
Budget/Entry Level: Intel Celeron or AMD Athlon
Basic Office Tasks: Intel Pentium Dual Core
Office Multitasking: Intel Core 2 Duo
High End: Intel Core 2 Quad
Memory and RAM
- The more memory you have the more programs you can run simultaneously and it’s best to have at least 1GB of memory. Faster memory speed will enhance overall performance allowing more data to be transferred in a given amount of time.
Hard Drive
- The hard drive stores almost all of the system data needed for your operating system, application programs and user data. Most business PCs come standard with an 80GB HDD since most files are stored on a server. Higher capacities are available at reasonable prices. Speed is really not an issue since almost all are now running at 7200rpm.
Optical Drives
- DVD burners are standard on desktop systems, but for security purposes, consideration should be given to determine whether or not your system should have these DVD writers.
Video and Graphics Cards (GPU/VPU)
- Although there are two types of video/graphics cards, discrete and integrated, integrated is the most popular choice for most business applications. Integrated cards feature graphic processing units, or GPUs, that are directly integrated in the chipset and require the use of system memory. Discrete video cards are designed for professional design and creation work where 3D imaging may be needed.
External Connectors
- More and more external devices need connecting, such as photo printers, scanners, cameras, etc. Consider the number of USB 2.0 connectors you will be utilizing and if a Fire Wire port is necessary. Also look for media card readers that support various flash memory cards for peripherals to be sure what you need is included.
Accessories
- Of course what good is a desktop without a monitor, keyboard, speakers, and mouse? Choosing the right accessories can be just as important as the computer itself. See our “Completing the Solution” guide in this section for more information.
What’s the Difference between a Workstation and a Desktop?
- Although the terms are often interchanged, a desktop PC and a workstation are not the same thing. Workstations are high performance computers that run intensive numeric and graphic applications. They utilize high speed processors, tremendous disk speed, and are all about power. Desktops are about flexibility and are designed for a variety of users with a variety of computing needs.
