The Llama King writes "The Houston Chronicle's Computing column has got the Doom 3 minimum system requirements. Biggest eye-opener: 384 MB of memory. Lots of mainstream PCs have been sold with 256 MB of RAM, so upgrades will be in order. RAM chip manufacturers should be salivating about now. You'll also need a 1.5-GHz processor and a GeForce 3 or Radeon 8500 graphics card or better."
