1) The gain of 70pts between P90 and MMX200 for Genius5 is not necessarily to
transfer to Genius3.  For Genius3 the step from 486/66 to P90 is factor 2 but
less than 60 points so what can we expect from another 2x speed P90->P200MMX?
2) I am not sure in how far 50% speed advantage would influence your 32pts
difference. 2482 is the value for MCP8, so do you expect Genius3 winning higher
against MCP8 because this is less than 2512 for MCP7? I don't.

Anyway, see other mail, it shows that indeed "old" programs are still on top
running on fast hardware! (at least Genius3 :-))
