For HD audio and video, you only have two options right now:
Intel - The G35
AMD - The 8200
The G35 has been out a lot longer, and works great. The 8200 is finally getting the bugs worked out and seems to be working, but the AMD CPU chipset and configuration can be confusing if you're not already familiar with AMD (e.g. not all Phenom's will work, and there are some very specific configurations it looks like you need to make to get things to work).
Check out the G35 and 8200 threads to see specifics.
In the not-too-distant future (i.e. likely Q4 this year), you'll have more options:
1) ASUS Xonar - HDMI audio card with HDMI video passthrough - allows you to use any mobo, and any HDMI gfx card, and get HDMI 1.3a HD audio + video. To me, this looks to be the best longer-term solution as you can buy the specific components for each piece however you want.
2) Intel G45 - An HDMI 1.3a upgrade to the G35, with improved performance.
3) Intel/AMD 8300 - An improvement to the 8200, and with Intel CPU support.
4) Radeo 4850 - A Video card with HDMI audio. Better than IGP, since you can use any MB you want, but your stuck with one card for audio and video, so not as good as the Xonar solution.
Anyway, that's the potential future, and who knows when it will arrive. Right now, pick your CPU, and then you pretty much have one choice if you want HD video and HD audio.
