Don't feel so bad. I know people that are getting similar benchmarks with more powerful video cards.
DOOM 3 is definately a hog. It's a beautiful game (when you're not in the dark), but requires a lot of horsepower to run.
I wouldn't blame it on ATI that much. the nVidia 6800 series does pretty well (GT and Pro), but that's because nVidia has always been better in the OpenGL department.
My only annoyance is they recommend SP2 for the drivers. I use a couple of applications that don't mesh well with SP2, such as "City of Heroes." Yeh, I have an nVidia, but I just hope other companies (such as nVidia) don't follow this trend yet.
SP2 is great, but their new code-security measures break things.
