This is deffinately not kernel related, but I can't think of a better
group of folks to ask this. If you know the answer, please reply via
private mail.
Anyone know what the heck Intel did to the MMX-Overdrive(150) to account
for this?
Thanks,
Mike

I actually bought the thing because I heard it had better floating-point
performance.. not a lie.. not even a damn lie.. a statistic. Byte benchmarks
gives me an index of 80 without MMX and 90 with.. none of it fpu related.
Consecutive runs.. 49 is Overdrive-150, 50 is Overdrive-150-MMX.
