First I bought the "Creative Sound Blaster X-Fi HD USB external sound card with THX" but again exchanged, because here no is 5.1 integrated. This external sound card with 5.1 then convinced me (under Win 7) as well as the owned internal card. The Dremel software with which you can adjust, for example, many sound modes, etc., was visually revamped compared to the previous I know something. However, you do not need a lot of settings when passing the signals in a reasonable AV receiver (who also various possibilities of sound enhancement features).
In "THX Studio Pro" the beige traditional software but leaves a lot to adjust to improve the sound of PC speakers critical (I use here in stereo speakers from Logitech). In particular, with the "Crystalizer" can more dynamic tickle in MP3 out and it can conjure up more space means "Surround". Installation problems I had not, everything went immediately around. Small defect which brings 1 star deduction is that only 1 optical digital output is available. Another coaxial here would be very helpful if all optical inputs are used by other devices to the AV receiver. Otherwise, the value for money seems to me even in the face of sound absolutely fine. That is why from me a clear recommendation for this even THX certified card ...
