I went to RAGE Steam page and i saw this:

Minimum:

Recommended:
OS: Win XP SP3, Vista, Win 7
Processor: Intel Core 2 Quad or Equivalent AMD
Memory: 4GB
Hard Disk Space: 25GB
Video Card: GeForce 9800 GTX, Radeon HD 5550

Is this legit? If it is... this game looks pretty optimized for AMD. Compare a 8800 to a HD4200 and a 9800GTX to a HD5500 is a bit weird. And wow 25GB for HD.
What u think guys?
