Most systems are coming with disks ranging from 8 to 16 gigabytes. Look for Ultra ATA drives with an access speed no higher than 10 to 12 milliseconds. The monitor is not a place to cut corners. Some of the initials and terminology here may be confusing, but bear with me. Your monitor should be capable of a resolution of at least 1024 pixels x 768 pixels.
Resolution is the number of pixels displayed on screen in vertical and horizontal direction.
The higher the resolution, the more pixels are displayed. A dot pitch of .26 to .28. Dot pitch measures how far apart the individual dots of the same color are on the monitor's screen. The smaller the number, the better. A refresh rate of at least 75-87 Hz.
