I'm looking to change my computer as mine is 5 years old - (it's getting to be a bit of a nuisance stoking up the boiler.) The ones I'm interested in mention that they have two, three or sometimes four PCI slots. Can someone please tell me what they are for - do I need to have a few spare.... sorry if it's a dumb question but I just don't know understand what they are for....
Thanks in advance,
Ian
