Thanks, NiukNiuk and Sazar. It worked.
Made a run with the Cpu @ 2,4Ghz.
NFSMW 1920x1440, AA Multisampling 4x, AF 16x, All in-game effects at Maximum, 25-30 fps @ 1920x1440 (2.764.800 pixels ... wow, that's 25-30 photos each with 2.6 MegaPixels , every second
anyway, enough about that ...
Fps is not on the safe side, gonna try to get 40fps with AA 2xQ and AF 8x
