hello. the GSX 1000 is actually a sound card that works great for 3D sound, music and movies. excellent for games (setting ingame separate cat possible). However, the settings are only essential and limited. There is no software or drivers to install. it is good, but if you need a custom equalizer, it will be very limited. There is also a speaker output, but only stereo. The sound and rendering of the GSX are excellent, but offer fewer settings than a conventional external sound card. It depends on your needs. Sorry for German ... google translate.
