Doom 3 Graphics

Do you think my ATI radeon 700064MB PCI or ATI Radeon 9250 256MB PCI can run the game?

Also i think the more ram you have, the better. Some games which you think might not run, could run and some dont. So its kinda 50/50 in some cases. I know my ATI radeon 700064MB Card can run GTA 3 and Vice City at near 60fps. Mostly due to me installing Intel Graphic Application 2.3.

I run the game on ultra, 1280x1024, everything max, full AA and AF.

60 fps in non-action scenes, 40-50fps when the action gets heavy.
