Summary: Ok, first, the headphone jack on the card is also the front channel jack (and auxiliary jack if I am not mistaken). So you need to hook up your front panel headphone jack to the cards on board output jack if you wish to use headphones and have front speakers hooked up at the same time.
Works, but you need to be a little bit of a nerd to get it to work on and Win 8.1 system.

Summary: Installation was pretty easy, although I had to trace the headphone/microphone connections in my computer to hook up my Sennheiser headset to this card, then I matched the "plugs". Neither my computer or the sound card had much in the way of documentation, YMMV.
Summary: This IS NOT ASUS' fault. The motherboard in the Dell Inspiron 660 does not properly support PCI Express 1x sound cards if you have any other cards installed. I happen to have an NVidia video card (EVGA GTX 760) installed.
Summary: Bought this to replace horrid onboard SoundFX sound on asus maximus hero vii. Just google that motherboard and sound problems. Yuck. Works well, many options in the drivers control panel Not shielded for EMI(electromagnetic interference) with some hardware.

Summary: For the price it is great. Has a headset amp for those wondering and mine did come with a low profile bracket as well as the standard bracket. You could get a much better one for more money, but if you are looking for a dedicated sound card for your system and not worried about full on professional...
Summary: I used the Dg for a few months and then switched over to DGX because my pci port was getting covered by a second graphics card. This card feels a little weaker than DG, but DG felt overpowered, which makes DGX somewhat balanced. And definitely better then the on-board audio.
Summary: The amplifier on this sound card is wonderful. I needed an amplifier, as my headphones were far too quiet. This sound card did the charm. I did not notice a huge improvement in audio quality over onboard (realtek 889) from the DAC, but it is still definitely there.
Summary: This sound card has a great performance for what it does. They are definitely better than any inboard sound chipset on motherboards, even $300+ motherboards. Definitely a must if you have an expensive pair of headphones as you will definitely hear a deference.
Summary: With a little installation effort and some consternation over the Windows 7 audio setup this made a noticeable difference in the system sound quality. For $35 I have no idea why I waited so long.
Cost-effective card for the mid-tier computer user

Summary: After getting this card, it's performance is pretty standard. The card sounds good, no extraneous hissing or popping,clicking,etc. A couple things to note. -Clearance - Ensure you have enough space on either side of the card, I had to finagle to clear my GFX card.
