Does your onboard sound support TOS-link optical out? If so, I'd hook that to your receiver. That'll provide better sound than the analog outs on just about every card out there. You'll be limited to stereo PCM, and bitstreamed Dolby Digital (some programs may be able to get DTS out also).

Other than that, I'd be looking for a new video card which has HDMI with built in multi-channel PCM sound, and run HDMI over to the receiver.
