Unless you can find someone with the same setup and trust them then I would simply check out the tested cards at http://www.matrox.com/video/support/.../rec/sound.cfm Personally, if it's not ion the list then I wouldn't trust it.
Alternatively, give one of the preferred system builders a call and see if they can offer some help.
