Basically a processor’s performance is measured with its “clock speed”, given in Megahertz (MHz) or Gigahertz (GHz, 1GHz = 1000MHz). These are the figures that will appear in computer deals and all sorts of advertisements. So its all down to the processor mainly, the faster the clock speed, the faster the computer will be.If you would like to save some money when getting a deal try not to buy the most top-end processors which are usually priced very high.

In computing, TFT monitors are rapidly displacing competing CRT technology, and are commonly available in sizes from 12 to 30 inches. As of 2006, they have also made inroads on the television market.

Graphics Card

The purpose of a graphics card is to present information in a visual form on the monitor of the computer. The specification of the graphics card will affect the resolution that can be displayed on the monitor and the “refresh rate” of the display. The refresh rate is the number of times per-second that the screen is re-drawn - a high refresh rate produces a flicker free display.
