It's creative x-fi surround 5.1 pro model (it don't have x-fi processor actually, just a fake named previous generation). May be i'm not lucky in life or what i expect is above reality, so can't recommend usb sound card after few hours of testing. It produce system lag (mouse lag too) when initializing audio device, including opening sound file if no other sounds playing and no software running which accessing to audio device already. Fast switching between tracks produce short click noise (don't know how it's in english). It's all usb specific issues. And the card specific issue is loud click noise when power is on/off, when os is loaded, which means it use capacistors without middle voltage point and without mute for protection.
I'm pretty happy with my RME Babyface here. Might be a bit overkill for your uses though.
Just wanted to clarify, that there's also good USB audio interfaces.
