Not many TVs can display 23.976 (24 FPS) multiplied by an integer (48, 96, and 120 being the most common values). Most take 60 in, or if they can display 96 FPS they take 60 and remove the 3:2 pulldown then multiply the original 24 frames.
the HTPC Gordon did is billed as 3D ready, and most, probably all, 3D TVs do 23.976/24 Hz. sure many people settle for 60 FPS, but that loses the "film" look that I and the wife like. mine does do 23/24/60 and a bunch more (confirmed it by reading the tvs EDID), hit "info" on the tv remote and it will display "24 Hz" during 24 (23.976) fps content.
All the HQV 2.0 (HD) scores I've seen place the HD 3000 (integrated in the 2500K and 2600K) around 100 to 110.
The new Radeon HD 6570 scores around 201. While those scores tend to be subjective, these seem to be average scores.
yup, certain ones in the ATI (err AMD) 6xxxx series seems to be best for HTPC use at the moment.
So what am I saying? If you're worried about it, substitute a Radeon 6570 (if you're only caring about video playback).
thats the point: you cant. with the build Gordon did that Im commenting on he mentioned it runs pretty warm as is, adding a 6570 to it might send it over the top heat wise. and definitely power wise, its a 120 watt PSU. it would need a bigger PSU, more cooling and an add on card.
Id be interested in any tweaks Gordon may have for it.
