The Xonar DSX is a mid-range audio card from Asus, designed for use in a PCI-Express x1 slot. It supports more channels and has a higher signal-to-noise ratio than the DG, but less advanced features and a lower price tag than the DX. If you want 7.1 audio support from a dedicated sound card this is a great choice, and a great upgrade from onboard audio. Support for EAX 1.0 / 2.0, OpenAL, and DirectSound is also there - along with Asus' exclusive GX2.5 gaming audio engine - making this a fine card for gamers as well as music and movie lovers.
Jeff Stubbers (Tier 3 Sales SME) Says:
Asus lists this sound card as having ASIO 2 driver support 44.1K/48K/96K/192KHz @ 16bit/24bit. So if you plan to run programs that need ASIO support, such as Adobe's Production Premium Suite, this could be a good sound card choice for you. This sound card comes with a front port header, to support audio to the front headphone/mic ports built in to the front of your case.

To piggyback on Jeff's comment, you can change the ASIO settings by right clicking the Xonar icon in the notification area of your desktop. It's a bit hidden, but the settings are there. I've needed to modify the settings to fix sound latency issues.

I recently swapped out my Creative Labs XFi Extreme Music card for the Asus Xonar DSX-PCI-E sound card after I ran into issues with the XFi card under Windows 8. The Xonar has been a nice upgrade in sound quality without any of the Windows 8 driver headaches I had with XFi. This drives both a 2.1 setup as well as all my headphone listening and it works well in either environment. If you're looking to step up from onboard sound to a quality all-around card, this is my first choice under $100.
