To make it easier to play Windows games, you can try PlayonLinux which allow you to install and configure games such as Call of Duty 2.

4. When I install and run a game it says that it cannot find OpenGL?

You need to make sure that the latest drivers for your graphics card are installed with Linux. Search for your graphics card maker (Radeon, Nvidia, Intel) in Software Manager to install the correct xserver-xorg display drivers.
Also, see the OpenGL website for more info on this technology.

5. What sound options can a Linux PC have?

Most PCs now have built in sound chips for producing music and sound, they can be adequate for most users but for better sound, you need a discreet sound card for higher quality sound such as the Creative range. The type of speakers you have also helps which can range from Mono (single speaker), Stereo (two speakers), 2.1 speakers (2 high, 1 bass), 5.1 speakers (Surround sound) and 7.1 speakers (surround sound with 2 more speakers).
