fastest floating point operation as possible

Hi,
I have a machine with a pentium4 2.52Ghz processor with 1Gig of Rambus
memory. I think the bus speed is 500Mhz (or thereabouts)? The machine is
about 1.5 years old.


The question I have is this:

Most of my computer work involves simulations that bring the processor
to its knees (doing floating point math). I am wondering if by going to
the newest Intel chipset (pentium4 extreme with 3.2HGz clock and 800Mhz
bus) whether I'll get a significant increase in speed beyond the sheer
clock speed increase? That is, will the speed improvement only be
3.2Ghz/2.5GHz = 1.28 (28 % speed increase), or, is the architecture and
bus speed going to give me much more performance than I currently have??



Thanks,

Paul
