Have an Onkyo 515 + ASUS P6X58 Motherboard... Do I need a sound card?

[cypherchild]

So basically topic title^

Full specs for audio system -

Onkyo 515
Wharfedale Diamond 10.4
Wharfedale Diamond 10.1 (Rear)
Wharefdale Diamond 10.SX
Wharfedale Diamond 10.CM


The sound I get currently is great... I'm just wondering, can it be better? I don't mind spending up to £100 if it's going to be worth the upgrade.

Usage in order:

Movies (commonly will only get movies with DTS tracks but if that isnt available will go with other formats).
Gaming
Music

Cheers, C.

Depending on your video card, your best audio output is via HDMI from your video card into your Receiver. Most newer video cards will output the best stream they detect and can decode via HDMI. Your receiver accepts Dolby True HD, and DTS Master audio from BD discs, as well as 7 channel uncompressed PCM via HDMI.

If you are a total fantatic about your 2 channel stereo setup, you could migrate to an M-Audio, or Asus Xonar card.

So no point then I'm assuming? I have a GTX 480 and will soon be upgrading to a GTX670. Music (and thus stereo sound) is a low priority for me, I'm more bothered about movies sounding as best they can.

Yep, both cards will output the very best sound formats currently available. Well asked question though!

Edit. Currently.
