I'd really like to use the 9600M GT all the time if Apple FINALLY (!) puts a fixed version of the last NVIDIA graphic driver update online! I have problems playing 1080i material smoothly like movie trailers on the Apple Homepage or iTunes HD content. (1080i *.ts or *.mpg material works fine.) As mentioned before in this thread, it is a well-known problem. If I can believe the forum people, this really was fixed by the last Apple graphic update. But as it caused a lot of other problems, it was stopped by Apple. I'm not willing to take the risk to download the old unfixed update somewhere in the net (especially because I use an external monitor which, as reported, is one of the main problem factors after this update), but I really want a fixed version of this driver!! How silly is it that I have to switch to my cheap on-board graphic chip to watch 1080i trailers??? The 9600M GT also gives me smooth eyeTV playback in fullscreen while having opened dashboard. The on-board version doesn't. Last but not least, I have the impression that Exposé works faster with the 9600 - show all windows and that kind of stuff ...
