The only 1080p content is HD-DVD and BlueRay. And I guess some 
European broadcasting of the air. Maybe HD-PRV but I don't remember 
if it can capture 1080p component. 1080i component yes.

Since 1080p is mpeg4/h.264 and there are no Linux hardware assisted 
video decoders for that type of content. It's a pure cpu decode game 
with video card possibly doing re-scaling with GL. Not to start a cpu 
war but the Intel Core2 Duo smokes the AMDs but they will cost 
slightly more. That E7200 will be plenty of ponies and also not 
require a wind tunnel of fans to cool.

Remember that a MacMini with 2GHz Core2 Duo and intel GM950 video 
chipset can handle 1080p. So any Core2 Duo faster than that or with 
better video is bonus.

Also remember that nvidia 8xxx/9xxx series cards do not have any XvMC 
decode ability but with an E7200 class cpu, you don't need it.
