XP home and dual processors.

XP home is limited to 1 cpu
pro does 2 cpu's

I haven't personally witnessed it, but understand Home will allow
hyperthreading on HT-equipped CPU's, so that might be a good alternative.

You need to look at what he is going to do with the machine. Most
home machines are used for the web, email, Word, Excel, etc. These
are all single thread programs (interrupts are a negligible load).
So, more than one CPU won't make anything faster.

Further, your hard disk is almost always the bottleneck as far as
speed goes -- look at what percent of the time your disk light is
on. Multiple CPUs will make this worse because one CPU will have to
sit there tapping its fingers while the other one is accessing the
disk. A faster disk (15,000 RPM from IBM) will minimize the
waiting. The right RAID configuration (striping?) should help.
SCSI interface doesn't make the disk turn faster so it won't help.

well, i think you'll struggle to attach a 15000rpm drive without using SCSI
personally...

What does IBM say about their product? How about Western Digital, which
also has a 15,000 RPM EIDE disk.

If anybody actually makes a 15k rpm IDE drive, I would be interested it
their model numbers.

Internet Explorer search for "15,000 RPM" found many. Here's a page that
compares them...

I thought XP home only supported one CPU, XP pro is the multi CPU support.
But then I am often wrong.

Thanks for the search, but they are all SCSI drives.
There were references to a 15k rpm IDE drive in the thread. and that's what
I would like to see a model number for.

15k rpm SCSI drives have been around for years now. AFAIK the highest rpm
for current IDE drives is 10k.

If there really is a 15k rpm IDE drive, I'd like to know who makes it and
what the model number is, so I can buy one.

As kind of a side note...While you're right about 15,000 western digital
has a 10,000 SATA drive, and I'm sure 15,000 isn't too far away.

You are entirely correct. XP Home is a SINGLE CPU only, XP Pro has dual CPU
capability.
