I bought a new Razer Carcharias headset and I wonder what audio card should I use.I currently use the motherboard built-in Realtek card,but I think it's not so good for gaming.Although I've upgraded my computer's GFX adn CPU several times,I never really cared about audio and I'm asking for your help.BTW I don't have a huge budget, so I'd be greatful if you could recommend something <50 euros.
