My friend has a Pentium M at 1.4ghz (laptop) and Doom 3 runs smoothly on it at high resolution... I'm a little confused... the min requirements says 1.5ghz on Doom3. How are you supposed to compare the speeds of a Pentium M and a Pentium 4. Cuz for newbies like me, when I see Pentium M at 1.4ghz, I picture this really slow *** computer that is out of date now... Can somebody tell me how Pentium M's work and although they are like around 1ghz they are fast as a 3ghz pentium 4 or w/e... I DON'T KNOW, SOMEONE CLEAR UP MY CONFUSION!!!! THNX!
