Thanks for the heads up concerning driver .340 <-> .343 and nvidia 8600 GT
So far it seems a good choice. The new card has DVI, the old was VGA, so the image is more brilliant. I have 5% more RAM available, video content seem to load faster (flash).
After some trouble with the driver (304 -> 340, worked ... until reboot. Turns out I forgott to purge the old one) now all seems to work well with one exception: flash (on some TV channels) shows wrong colors. It used to work with the old card, even today when I looked a soccer game (ZDF). In the pause I change the card and the colors went sick.
Towo told me to disable hardware acceleration in flash, but I connot reach this setting in the flash context menue. It freezes or does not accept changing tabs. (In the past I had flash versions who's settings I could change and versions who's settings dialog freezes everytime I tried to change something. The last version .400 seems to belong to the latter group)
Is there a way to disable hardware acceleration in flash within a config file? What else could I try?
Other than that, the new card seems a good investment.
Edit:
wrong colors in flash problem is related to Opera browser 12.16.

Edit2:
wrong colors in flash problem is not related only to Opera. Midor and qupzilla showed wrong colors, too FF/IW didn't. But with midori, I could access the flash context menue and disable hw accelleration. Now all browser show right colors and I can use Opera again but all mentioned browsers now constantly need 90% to 100% CPU power which makes me feel a bit concerned about CPU lifetime.
