Those system requirements cant be entirely correct, especially the video card requirement.
-How is the GeForce 8800 an equivalent GPU to the Radeon HD 4200, which is an outdated IGP?!?
-How is the ATI Radeon HD 5550 and equivalent GPU to the GeForce 9800 GTX, when it is over 150% faster?!?
-How come the difference between Nvidia's minimal GPU and recommended GPU so dismal and pretty much irrelevant?!? The GeForce 9800 GTX is a lightly overclocked GeForce 8800 GT.
I guess PR forgot to run these system requirements by Carmack. Mind you, Carmack said by the time the game ships, Rage will run @ 30FPS on the Sandy Bridge IGP.
