I never had any issues. I did have a wake from sleep problem AFTER the firmware but something subsequent seemed to have fixed that. I run CS3, FCP, LR, Motion, Compressor- often multi-tasking and haven't felt the urge to upgrade to the Nvidia. I originally bought Octo with the ATI out of sheer impatience but it's done so well I'm happy with it, at least for now. I play a lot of EQ2 in BC as well, all settings on high and it screams.
