[mythtv-users] Operating System of choice ?

[mythtv at sci.fi]

Kinda related to the topic, has anyone had any experience running any OS 
(FC4 for instance, but should be the same with others as well), with a 
MoBo that has integrated gfx ? In theory DVI-D should be the same 
regardless whether it's coming from the MoBo or GFX card, so how's it 
work in practice ? Is there some advantage/reason to use a gfx card ?

What I'm thinking here is quite simple, is there performance and more 
importantly quality differences when comparing a gfx card and MoBo 
integrated gfx, assuming both use DVI-D, since IMO both the integrated 
and gfx card should give out the exactly same DVI-D output, where as in 
analog the D/A conversion might have differences between cards and 
integrated.

My idea is to build the system using a backend on server and frontend on 
a "hifi" desktop pc, so I'd like as stuff in the desktop machine as 
possible. Also anybody have experience of using that kind of "terminal" 
as frontend.
