Advice Required: Can I use PC Speakers for PS3?

[CossackNoodle]

I basically want good 5.1/7.1 speakers to use for my PS3 and was not sure if i can just connect the speakers straight to the PS3?

Would really appreciate your help

I know the PS3 can accept optical but I wasnt sure if pc related speakers support optical or need a sound card to get dolby digital etc?
