I think this thread is off on the wrong tangent. You need a good video card for HD playback on a desktop system, right? Then I recommend the ATI HD2400 series or 2600 XT. These have far and away the best hardware acceleration for High Definition playback. Furthermore they support Overlay playback. This is where video playing in Media Player or the editing window on the main monitor plays fullscreen on the second monitor, even to an NTSC/PAL monitor. Memory amount isn't all that important, and maximum resolution playback takes only 24% of the GPU's reosurces and virtually NONE of the CPU's.The Nvidia 8800 series won't do this at ALL! It has no Overlay ability for "Zoom mode" in addition to not having such good hardware support for video.
Also prices, the 2400 and 2600 are $55 and $100, the 8800 is $330+. The ATI HD2900 XT at $450 does NOT have full hardware support for High Def. (yet)
