I got my radeon 64mb drr vivo today. I installed it and tried different buss speeds to get 3dMARK 2K1 to run stably, got it to run stable. Then I tried it with the Beta drivers, and my system got all messed up!!!! I removed everything buy un-installing it and then rebooted with it as a standard vga display adapter. Re-installed and my 3dmarks are all shot to hell!!! My framerates suck now!!! PLEASE HELP BEFORE I GO CRAZY!!!!!!
