What kind of graphic card do i need to watch hd-xvids and other hd material on my hd flatscreen tv. Is it necessary that the card has HDCP support? Im buying a new computer and i dont know wich graphics card to choose.
Yeah, for high resolution DivX or XviD files you do not need anything really special.
However, if you want to watch Blu-Ray or HD-DVD, then you're talking about some serious hardware. I suggest you read the following article from Anandtech about HD Video playback:
The 8600 series from nVidia and 2600 from AMD both support hardware decoding for some video codecs so that should help. I could watch the Harry Potter HD (720p) Quicktime trailer without any hiccups on my Core 2 Duo 6420 + 8800GTS with the CPU utilization in the 8-12% range. I've never tried any HD XVid or Blu-Ray etc. so can't comment about those.
