Dear Sirs,
I have a little trouble with my video card:
GeForce 6800 256Mb Ram PCI-E 256bit DDR3 (on nForce4 s939, with DVI/VGA monitor LG 15")
Help me please.

PS
All another things works very good, and in "About this mac" i see my videocard with right name and ram size, but videostreaming is too bad, screensavers works steply(with a low fps)
