You're right, I should have stated that I'm mostly gaming and listening to music. I've recently gotten hold of the software I need to connect my guitar to my computer and use it as amp, so I'll be venturing that way soon. The alternative I was considering was the Xonar DX, but the only place I found who had it in stock was on a 7 day delivery. I'm however really desperate for a soundcard. I need to recieve it yesterday, so I can determine if I want to keep the Roccat Kave (I can only return it within 14 days of recieving it, got it yesterday). The Roccat Kave is on paper a great surround headset, but since it doesn't have build-in soundcard (which somehow pleases me as that type of soundcard usually is crap). I should have thought of that before buying, but I was stupid enough to believe the my onbaord was enough (durr, clever me)
From what I've read so far, the Xonar DX and the Titanium are roughly equal, but since the Xonar is cheaper, it usually wins the tests. What I also read though, was that Asus are slacking with the drivers, where as the drivers and software for the Titanium has got some great reviews (once you finally get them installed)
And please don't bring up the fact that Gaming headsets are bad for audiophiles, I know that, but I'm not dishing 150€ out for something that doesn't have a mic when I'll be using it for gaming. If I were to buy a quality headset, it'd be a 300€ + headset, but unfortunately, my budget doesn't support that (I'm a student)
