pc + speakers what goes in the middle?

[turbotoes]

Ok I'm new to all this fancy sound stuff, and have been asked to Join up a pc and two fancy Audio speakers (can't remember the name)
I think I've got figured out what I need to do the job

1 sound card with a digital output = Terratec Aureon 7.1 Space 8Ch

1 a/v amp with digital input = Yamaha - RX-V359S

so sound card in pc, digital out to yamaha thing = itunes on the speakers, I hope :~)

Could one of you audio experts tell me if I've got this right or totally got the wrong end of the sticky thing.

ps if you've got suggestions for better kit for under three hundred british ones ( £'s)
tell me

cheers much

thanks for that, I went for the 5-1 jobbie because that allows for future upgrades, and I wanted the digi output ( the guy is a bit of a sound freak) its not my stuff but I do like to allow a bit of expandability .
glad to know I was pootling along the right lines!!
thanks
