Desktop recommendations

Processor

• CPU Comparisons (from Tom's Hardware) 

Operating system

• For workstations, the Library Commission recommends Microsoft Windows Vista Business or Ultimate edition.

• The 64-Bit version of Windows is a reasonable option. Check your mission-critical software for compatibility issues.

• Vista Versions

Memory (ram)

• 2GB minimum, 4GB if feasible• (more is better, but 32-bit

workstations can only  fully utilize approximately 3.5GB)

Hard drive

• 120GB or larger

Video

• If the workstation will be used for gaming or Second Life, be sure to specify a compatible video card.

• Video Benchmarks (Tom's Hardware) • Second Life System Requirements

Sound

• Be sure to include speakers and/or headphones as appropriate.

• Microphones are not a bad idea any more.

Removable Media

• Have plenty of USB ports on the front of the computer.

• You really don’t need floppy drives any more.

Media Reader/writer

Keyboard and Mouse

• Keyboard and mouse may use either PS/2 or USB ports. If you are planning on re-using an existing keyboard or mouse, be sure your new computer includes the necessary ports or adapters.

• Note: the same caution applies to barcode readers, trackballs, and other input devices.

Network Card

• Gigabit Ethernet card

Printer

• Ink-jet or laser printer • [Higher resolutions are better: 600

dots per inch is better than 300 dpi, for example. Higher pages per minute ratings are better: 8 ppm is better than 4 ppm, for example.]
