What kind of PC do I need to run Linux?

Getting the drivers you need for your PC used to be one of the biggest hurdles to overcome for Linux newbies. Linux supports less hardware than Microsoft Windows, but if you have a reasonably new PC and use one of the common distributions like SuSE or Fedora you should be OK. The Linux driver support situations is gradually becoming better and finding drivers for the most common graphics cards, sound cards etc. should be no problem. The most problematic devices to get drivers to are often win modems and windows printers. If you are concerned about 3D graphics performance you should go for a graphics card based on chips from nVIDIA. They provide Linux drivers for their accelrated 3D cards. Several PC suppliers can deliver PCs with Linux preinstalled, in which case you don't have to think about hardware compability at all.
