What would sound superior

[Aviince]

For my gaming sytem I  have been using a ASUS Xonar D2X sound card with some old 7.1 speakers and a set of sennheiser 558's wich sounds great altho i just got given a really nice sourround system as a wedding present (for the lounge room) and now the 5.1 Yamaha htr-3066 reciver and set of nice 5.1 speakers that i had before is gathering dust, my question is would there be any benifit in sound using my old 5.1 setup for my gaming pc or is my currnet sound card / speaker setup better than that of this reciver? asuming that if i was to use the reciver the sound card would be doing almost nothing other than Encoding over SPDF as my board only supports 2.1 over SPDF?

 

Thanks for any help.

I assume that the reciver would be better, due to how much it costs lol.

It's very likely that the receiver will sound better. Its amp is probably far superior as well.

How is a sound card driving speakers in the first place?

 

If they're active speakers, I imagine there's not much of a difference between the two sources.
