I have _lots_ of data.  I have run on ICC for years now, at in blitz games,
switching to
2x faster hardware doesn't have an appreciable effect on playing humans...

Not really.  There are a few gms that get a significant number of draws to go
along with
their losses, and they even win a game here and there.  Going from 4x400 to
4x550 to 4x700
and even 2x2800 does not make that much of a difference.  I have even changed
from 4x550 to
2x2800 and then later asked them if they could tell any difference.  The answer
was "no".
