Forget the sound card to your motherboard

Installation is no problem, drivers are not intrusive and are limited to the Music Center, which includes all possible settings for the card.
HD Audio compatible, so it automatically detects when a headset is plugged into the front output of the PC and the HP cut plugged into the rear exit. The integrated amplifier dedicated to this event before permits to increase the gain if there is a branch HiFi headset high impedance. With my AKG K242 mediating the setting is more than enough.
And the sound quality is really excellent. No more details muffled, low embedded in each other, we finally find clarity and definition that give momentum to the music. This quality is also reflected in games, although here I have not been able to evaluate the benefits of the support EAX effects normally possible GX mode.
For the price, if you're a music lover and not listen to bad headphones on your PC, you will enjoy as I think the difference compared to a standard Realtek chipset.
