CPU

Look at any PC advertisement. The first specification given is usually the CPU speed, because PC buyers like to be able to compare numbers, and this is an easy number to use for comparisons. Ironically, most PC systems are not balanced: a high-power CPU is wasted on an inferior bus and disk. (On the other hand, the CPU isn’t really wasted from the PC maker’s point of view if that’s what gets you to buy the system.) A low-end Intel Pentium CPU running at 500 MHz will end up spending most of its time waiting for its EISA bus and IDE disk. What you really want is a fast bus, a low-latency disk, and a lot of RAM. Systems sold as servers are generally better balanced, because they are rated on actual throughput.
