ok, i'll try to be short...i installed Daryna 4.0 KDE CE, also installed nvidia drivers for my Gigabyte GF6600GT silent pipe...i started installation through Envy system, and after i chose automaticaly setting configuration...restarted machine, and on the next boot everything worked awesome, i had normal refresh rate, resolution, all fine. But, when i checked the settings for graphic card in system settings-->peripherals, as default my graphic card is recognized and set as GF6800XT, but in nvidia settings as correct 6600GT, so i'm wondering, i dunno, according to fine display configuration(refresh rate, resolution), i have no other graphic problems, maybe those two cards has some commonly characteristics, and 6600 share same configuration... but, when i set conf. for card as nvidia 6 series in settings, on next boot, i loose 3D acceleration, yeah! so my question is, if i leave this alone, settings as 6800XT, could this damage graphic card??
