i recently bought a loaded laptop with xp home on it, how
ever i believe that i will be able to achieve much better
performance if i replaced the OS with windows 2000 pro, i
just needed to know if tha would work, because i have read
at several places, that it does and at several places that
it does not. thank you so much, the following are the
system speceifcations.

P4 2.8Ghz, prescott core 800mhz fsb
512 mb dual channel pc3200 ddr
hitachi 60 GB hd
ati mobility radeon 9700 64 mb

The correct answer to your subject line is, "sort of".

Unlike XP, Win2K cannot distinguish between physical and
logical processors. So it will see one hyperthreaded CPU as
two individual CPUs. It will definitely work, but depending
on your particular system you may want (or, in rare cases,
need) to turn off hyperthreading in your system bios.

The performance benefit of hyperthreading is next to nothing
in many cases, especially on a laptop.

Any performance increase will, at best, be marginal. Some benchmarks
favour 2000, others XP. In reality you're unlikely to notice any
difference. On identical hardware they two OSes tend to give very
similar performance in real-world applications.

It would certainly work, assuming you can find Windows 2000 drivers
everything.

This will be a Hyper Threading CPU. Windows 2000 doesn't support HT
properly so you'd probably be better turning off this feature in the
BIOS.
