7.1 systems and Xbox Help!!?

im looking into buying a 7.1 system and was wondering, I know neither xbox or ps3 suppost 7.1 in the games but can you still use all speakers? or would I have two speakers doing nothing?

I mean like the Rear back and rear left play the same sounds, etc.

I have owned a 7.1 system for two years and all 7 speakers play sound and sound amazing! So totally get a 7.1 because it uses all the speakers and sounds amazing!

so your system plays basically 5.1 but uses all speakers( 2 sets of speakers playing same sound i assume ) ??
