The best configuration would be 8600 GT+9400 in the extended desktop mode; connect 8600 GT to the display directly (primary display) and 9400 to AVR (secondary display). Then you will get the best of the two GPUs (good gaming/video playback with 8600 GT, and 7.1 LPCM HDMI audio with 9400). Check the mATX mid-range Intel/NVIDIA system in my recommendations.
Thanks for the suggestion. I have read your guide

This is a good immediate solution to be able to feed 7.1 LPCM to the AVR while keeping good video performance, with one extra HDMI used.
In your mATX mid-range Intel/NVIDIA system in your recommendations, you suggested the Core 2 Duo E7400 2.80GHz Socket 775, $133.
VS the
Athlon X2 7750 Black Edition AD775ZWCGHBOX 2.7GHz Socket AM2+, $79. that you mentioned before to go with the 780G.
$133-$79 = $54 more.
I am aiming to build a budget HTPC, so I guess Intel CPU does not favor me.
In Regard to having LPCM 7.1 for TrueHD, TrueDolby+ fedelity, I do not need them at the moment as I do not have the budget to upgrade my current Panasonic PCM DD 5.1 AVR setup which still uses only S/PDIF, no HDMI input.
I have PSB for the center spkr, PolkAudio for the fronts, Jamo for the rear.
Would you suggest getting a motherboard with LPCM 7.1 via HDMI now just to be futureproofed when I upgrade to an AVR with 7.1 HDMI input after 2 years? Or just get a 780G with S/PDIF now for less?
For me, I think the 7.1 standard is not fully mature.
At least not all blu-ray disc contains a nice decent 7.1 track.
Also, people on this forum say the SNR or the noise floor of computer sound cards are just not good enuf anyway to reproduce any high fidelity sounds. SNR is never as 124dB as they state after all the other crap (components)along the way of the connection to the AVR.

I believe they kinda misled people as 124dB is stated from the output of the DAC of the sound card and not from the final output jack. Agree or Disagree?

Another option is
- Athlon X2 (Socket AM2)
- 780G mb (IGP is not used unless you connect more than two displays)
- Radeon HD 4670
HD 4670 is better than 8600 GT in gaming (3DMark06 7500-8000), best in post-processing and supports 7.1 LPCM over HDMI. Check the mATX mid-range AMD/AMD system in my recommendations (the processor there is Phenom X3 8750, but you can choose any).
I do have an AMD system with Phenom X3 8450, I do not know if the 8450 can do the job properly with the post-processing. Would that do the job?
