Best soundcard for under £100

[Matf661]

My system specs are:
Gigabyte ga-z77-d3h motherboard
GTX 670 OC windforce edition
16GB Ram
800 watt PSU
Intel i5-3570k 3.4ghz
Tp Link 300mbps WiFi card

And Logitech Z-906 5.1 Surround Sound Speakers

I'm looking for the best soundcard for use with these specs. I mean best in terms of both quality and driver support. It will mainly be used for Drum and bass music and gaming, with preference towards music quality. So which Soundcard is best suited for this?

do you really need a sound card? have you tried out the onboard yet?

also, change some system specs

-down back to 8gb of ram if you are not doing work.
-get a i7 if you are doing work
-you only need a 750w and a good 750w, not a pile of junk 800w

something like a asus ds 7.1 or a dg 5.1 will be sufficient for you if you really need a sound card

The best sound card is to use the one that is already build in these speakers. Connect it to the optical output of your onboard and enjoy.

Well thanks for the constructive criticism, however I'm not gonna take stuff out of my already built computer and pay extra... But cheers for the soundcard recommendation.
