The eye can see a huge "framerate"... just depends on what the source is (light vs dark, movement vs no movement, etc)
Anyway, original Crysis or Crysis 2? Original Crysis should play at max settings but with 2xMSAA, Crysis 2 should play pretty well at max, except that Nvidia gave them code to use for tessellation that is absolutely fucked and tessellates the *** out of concrete blocks as well as renders the entire ocean underground at all times.
Not sure about WoW...
Anyway, run 3DMark Vantage, you should probably get around 25-30000 points (Performance setting).
