Upgrade suggestions

Dear Tek Syndicate,

I a, having a hard time deciding what to upgrade next in my pc. Right now I am stuck between getting a Sound Blaster Zx soundcard or just getting an ROG Crosshair V motherboard that has an mid-grade soundcard for it's onboard audio. I would like to here some recommendations for you guy, and if you want to know my specs currently they are on my profile page and will be updated soon. 

Buy the better mobo. you don't really need a sound card unless you are a audiophile with really high end headphones
