You can save the money with the GPU if your not gaming with it
If you are an Nvidia fan than the Gt430 would be fine at half the price
it has Blueray 3d playback and TrueHD and DTS-HD Audio Bitstreaming Support
You can see here on Newegg http://www.newegg.com/Product/ProductList.aspx?Submit=E...
Also a HD5670 would be a good option also
if you dont mind Ati/AMD
Using the HMDI on the card would be a good option for audio with that card
And you could still game at reasonable resolutions with medium settings
I still have a question:
Comcast is doing encryption for a lot of the channels, if I take the cable from Comcast STB and plug the cable in the MediaCenter and from there in TV do you think this is going to fix the problem with the encryption ?
