I have had problems with my 6800 ultras
I have had driver problems with my 6800 ultras as well and have even had the GPU crash when playing a game and I am using the newest drivers and I know my system's hardware is not the problem I am leaning towards the fact that it is either that there is still a problem with the coding of the driver or it is a problem with windows. I should have it trouble shot soon. The problem I have ruled out of being my CPU, PSU, BIOS settings, and the hardware. I belive it to be (1) a driver conflict of somekind, (2) unknowen problem with the O/S, (3) Game/program compaditability problem, as Half Life, Half Life2 and TFC are the games I normaly play and there are some minor issues I have had in these games. One problem I have had a few times I have had with thes games With another computer that is a P4 with an Ati card so my AMD with nVidia cards are ruled out on that; on the P4 I played around with the setting and the crashing stoped but one of my problems seems to still be there with the nVidia Card(s) " it is mor prominent when I enable SLI mode but is hardly noticeable With one card, other then in HL2. I get the lines either way so I play that game with both cards.
