when running the benchmark it shows CPU original clock speed rather than OC value. i think it only reporting what cpu you have and not your actual cpu status running at certain speed. did you turn on the v-sync option? if yes that might what limiting your frame rate. but i also heard some people with ati card have lower FPS when playing RE 5 but i'm not sure why though
Wow that is depressing (lol) a 4870 scores the same as me. Drivers that I have currently installed are the latest from Ati with date 10/13/2009 ,BTW during installation got an error something like "ati catalyst install manager install package failure" ,strangely just ignored the message and the installation was complete also looking at the "view log" shows everything was a "success"
