Pros: Windows 7 64 bit installed automatically, Sound is decent. Worked with my Dell Studio Desktop. Great Price

Cons: None so far.

Overall Review: This is the first sound the computer has made! My 3d Sound USB c-media adapter was not Windows 7 compatible and the on board Realtek sound card was digital only, no Analog even after messing with their Sound Manager. Which is typical for this dell studio desktop 540.
