HTPC Noob needs wiring help

[Liberator21]

I'm about to delve into my first HTPC project, and need some help. Actually it will be my first decent HT project. Here are my components, please tell me how to connect them if you could:

HTPC:
Used for TV recording and music playing
TV + small LCD for monitor, mainly TV
Motherboard has HDMI
GPU doesn't have HDMI, only S-video

TV:
Westinghouse 37'' 1080P
Also be computer monitor

Audio:
Unsure yet but will have HDMI

Now will it look something like this?

PC -> HDMI -> AV receiver
PC -> HDMI -> TV
TV -> HDMI -> AV

That doesn't really look right to me, surely there's more than just connecting HDMI's to everything. I know I'm a noob!

So if you are going to be using a seperate GPU you will need to run a DVI->HDMI converter to your TV. Then you will also need to run the onboard sound(if this is transmitted over the motherboard's hdmi) to your receiver.

If you got the ATI HD2400 or 2600 they have the DVI > HDMI adapter. They also passthrough 5.1 audio (no lossless though) through this port. So you could go from PC > AV Receiver > TV and get 5.1 and 1080p. These cards also will handle HD video decoding and processing so you can relieve the CPU from doing this task alone. I believe that the Nvidia 8500 and 8600 cards have this same capability but I don't know if they come with the required DVI > HDMI adapter in the box.

Or you could do HDMI > TV and then run 5.1/7.1 analog output to your receiver allowing your DVD software to decode the TrueHD and Uncompressed PCM audio and use your soundcard(onboard works too) to output it directly into the receiver. You won't get full lossless TrueHD (limited to 16bit 48khz I believe)and cannot do DTS-HD Master Audio at all. The benefit is that you can't even get lossless out via any other method and even the lower quality TrueHD is better than DolbyDigital Plus. HDMI from a PC won't bitstream trueHD or any other form of lossless HD audio.
