I'd like to buy the one from CCL Computers : www.cclcomputers.co.uk

Thanks

BTW, any links to info on overclocking it ? I've just about decided upon
the MSI 865PE Neo2-PFISR. What are the odds of getting to overclock ?

And one last question : the stock cooler on my Athlon XP is far too noisy.
What about the stock Intel ones ? I know for sure that the P4s in
enterprise small form factor machines make no noise at all even with a fan
running.

Thanks again

Dunno. The Dell Optiplex SX270s we have at work can get a bit noisy,
although it's a laptop type fan (not quite so high volume, but quite
high-pitched compared to a typical desktop)

The stock intel fan that came with my P4/1.7 ages and ages ago is reasonably
quiet. YMMV.

I'm not sure about the hyperthreading. However, I think its a moot
point at this time. The published benchmarks show no real advantage
over the Northwood P4s with existing software and the evidence is that
the power dissipation of the current Prescotts is considerably higher.
Unless the fan on your Athlon XP is a lot noisier than the one
provided with recent AMD retail cpus, you are not likely to achieve
any noise reduction with the cooling system you would need for
overclocking a Prescott.

The enterprise machines you are referring to have carefully designed
cooling arrangements and usually have the advantage (from the cooling
perspective) of having relatively basic video cards - this accounts
for their quietness.

If you have your heart set on a Prescott, I would wait for the next
stepping - I would expect that intel is working hard to get the power
dissipation down.

To be honest, it's been hard to choose between :

* changing the XP 2000+ for an XP 2800+ and still use my MSI KT4V board

* changing the processor to a 2.8 Prescott and the board to the better of
the MSI 865 PEs

* changing the processor to the Athlon 64 3000+ and the board to
something suitable - not sure which

I want to be ready for Doom III and Half Life 2. I know I could wait but
the prices are so cool right now (and yes, I understand that they may go
down before the games are released).

The first option would require me to swap out my 768MB DDR 2100 for a 512MB
DDR 3200 but for the same price as the second option I could also replace my
64MB Leadtek TI4200 with a 256MB Sapphire 9600XT. I guess that I would end
up with a more rounded system that way. The benchmarks on Anandtech / Tom's
are not that helpful as the results are just not clear cut. The thought of
the 800 MHz FSB and the chance to use the dual channel capability combined
with what I understand is the P4's ability to shift the data to and from RAM
so efficiently are also appealing.

Even as a long term AMD user, the Athlon XP 2800+ sounds like the poor
relation to the P4 2.8.

Any thoughts, anyone ?

Thanks

You mean the article that is now 4 months old based on rumors from
before the chip was officially announced?

Come on! Don't bother with these outdated rumor mills, go straight to
the source. www.intel.com has all the info you need here.

In short, the P4 2.8A GHz processor is based off of the Prescott
(90nm) core, has a 533MT/s bus speed and does NOT support
hyperthreading. The P4 2.8E GHz processor, also a Prescott chip, has
an 800MT/s bus speed and DOES support hyperthreading.

So, is it same to assume that any P4 2.8 GHz processor with an 800 fsb WILL
have hyperthreading ?

As it stands now, yes. Intel may change that policy at some point in
the future, but I highly doubt it.

The Intel HSF's are certainly on the quieter side but not silent. My
P4 1.8A came with a fan that runs at 2200rpm, my P4 2.66 came with a
slightly larger fan and it runs at 3000rpm. But you can always slow
them down with a Zalman Fanmate, they only cost a few bucks. I OC my
2.66 to 3.0ghz though so use a Vantec Aeroflow on it which is quite a
bit noisier than the Intel fan. I make it a bit quieter by having my
mb slow down the rpm though.
