was bored today and didnt feel like playing Doom 3 during the day so here's a few tests that I did out of boredom:

No AA in any of these tests

P4 [email protected] high settings 1024x 4.7 catalyst = 31.7FPS
p4 [email protected] high settings 1024x 4.9 catalyst = 32.8fps
p4 [email protected] high settings 1024x 4.9 catalyst = 34.2fps
p4 [email protected] ultra high settings 1024x 4.9 catalyst = 28.9fps
p4 [email protected] ultra high settings 1024x 4.9 catalyst w/rage3d tweak utility = 29fps

Not exactly the highest of scores as you can see, but actual gameplay runs better as the timedemo is made to stress your video/cpu performance.

As you can see, CPU difference of 400 mhz only makes a difference of barely 2 FPS...so its not the bottleneck, neither is the memory...and you really can only overclock your video card so much with this game.
Surprisingly, ultra settings dont bog down my system as much as I thought they would.
I definitely recommend getting the BETA 4.9 drivers as it gave me a free FPS and got rid of a few visual artifacts it seems.

Enjoy, maybe these will help someone base their scores off of.
