Nice SS. Do you have any tearing with your video card while playing videos with X composite enabled? I have a GTX560 and I still can't play flawless videos in linux/bsd. In Windows it's fine. If I disable compositing, it's fine.
Im running the latest nvidia beta's and so far I havent seen that much tearing, I did however had some horizontal refresh/tearing issues with the previous drivers (not as bad as it used to be but still noticeable).
Only thing i have noticed is a vertical tear (at the right side of the screen) for some reason, but it seldom shows and usually only after I just logged in.
