What does it do? (4 of 4) Part 4 - Graphics Card

So we've covered the CPU, The RAM & the Hard Drive.  So now it's time to discuss the roll of the Graphics Card.

The Graphics Card is often a bit of an unsung hero, and most people will opt to buy a PC with a built in Graphics Card.  While this might seem a cheaper option at the outset, you can buy some really good base level graphics cards for relatively low amounts of cash.

The Graphics Card is the interface between your computer and your Monitor. It's job is to calculate exactly what you see.  While that might not seem to be too difficult, the quality of the graphics card and the speed and memory of the card can make a huge difference to what you see and the quality in which you see it.

More evident in graphics intensive game and applications, the Graphics Card will also TAKE AWAY a big workload from your CPU.  This means that with a relatively cheap installation of a Graphics Card, you could find yourself improving the overall performance of the computer.

High End Graphics Card support higher quality resolutions, faster frame rates (how fast the screen refreshes and reloads - the faster it is, the smoother it looks), and additional monitor ports or HDMI ports. (HDMI is a port in which you can plug your High Definition Television into)

With the rise in high quality films and blue ray players being available to play on your computer, a good quality Graphics Card becomes apparent.
