Silverman then went on to list his own recommendations about what gamer's will need to squeeze the most out of
Doom 3. These included a 3 GHz processor, 1 GB of RAM and a GeForce 5900XT or Radeon 9600.
Bottom line, this game is going to take a monster of a system, so if you don't meet the stats its probably a good idea to start looking at upgrades now. Then again, you could always wait for the Xbox version, which should be out in October.
Doom 3, for the PC, ships on August 3 of this year.
