Q: Will my computer run DOOM 3?
A: Id software did tell us that 1GHz CPU 256MB RAM GeForce or Radeon 7xxx series card will be the minimum requirements, it is the minimum and I wouldn't expect you to be able to play with very many, if any of the features turned on and you wouldn't be leaving the world of 640 x 480
As a reference of what we think:
• 3+ GHz CPU, GeForceFX 5800 and above class GPU, 512+MB RAM RAM - Great system, framerates and gameplay
• 2-3 GHz CPU, GeForce 4 class GPU, 512MB RAM - With that kind of setup you'll be fine and enjoy playing Doom3
• 1-2 GHz CPU, GeForce 3 class GPU, 256-512MB RAM - average system, average framerates
• 1 GHz CPU, GeForce 2 class GPU, 256MB RAM - Playing at medium settings won't do it
A Pentium 4 or Athalon XP, 512 megs of RAM and a video card such as a Nvidia FX 5900 or a Radeon 9800 and sound card that can handle 5.1 surround sound will give you the full experience of DOOM III.
