Upgrade Sound Card ? Or Upgrade Headset/Speakers

[TaKeN]

I currently have the Creative Sound Blaster Audigy 4 7.1 EAX Sound Card - OEM paired with a Speedlink Medusa 5.1 Headset..

Should i get a suround sound 5.1 system for my pc room, or upgrade my Sound card to the Fatal1ty FPS or XF-I OEM..

I was looking to spend £200 max on either.
