Very high end? Like.. better than 1920x1080p? You'll never have a  
video source better than that. At least.. not in MANY MANY years.  
Instead of making ambiguous statements like "high end", I would ask  
specifics like.. "HOW high end?" and "Why?"

I have an nvidia 6100 that cost about $30 and it looks exactly as good  
as the video card I spend $300 on last year. The $300 card is great  
for games. They are exactly equal for TV.
