OK, if one adds 90 points. But it was not what one could have expected because
the jump from 486/66->P90 was less than 60 points!
I'd have expected 50 pts which makes 2460 and 166MMX reduce max. to 2480 (MCP)
and therefore a close win for MCP.

If you add 90 pts (!) for Genius3 P90->200MMX, it would be higher rated than
Genius5 in SSDF. :-)))
(I know, only 4 points but not as worse as one could expect by the huge version
number difference that should indicate major changes).
