whit today's programs and games the p4c800e deluxe with a 3.2 extreme or
another high end asus board that I can use my 8 x agp video card an ati x800
se 256 and the new Intel 3.2 d or amd dual same speed thanks.I am doing a
new acrylic case and not sure to get new board and cpu or keep my 3.2
Prescott or could get a 3.2 extreme for it .

First off, here are some AGP and some PCI Express benchmarks. Not all
the current video cards are shown, with the newest Nvidia (7800)
and the just released ATI x1000 series missing. What this shows, is
that having a PCI Express motherboard allows newer faster video cards
to be used, while if you bought an AGP motherboard, you would be
"stuck" with the cards that are currently available for AGP.

Only so many LGA775 motherboards are dual core ready. The rest are
single core ready. On the AMD side, at least with S939, more of
the boards handle both. In my mind, dual cores are still a bit
too "forward looking", unless you are constantly running long
computations running at 100% while trying to do other work. It
will be a while before a lot of computer games will use both
cores of a dual core. And even the games that do use dual cores,
won't run both cores to 100% (threads handling different aspects
of the game, like video output and AI, will not likely load the
cores to the same extent). There may be other ways to slice the
workload, but I would not expect a doubling of output.

Tomshardware also has CPU charts. Select the various benchmarks,
to see how an Athlon64 compares to a P4 at various speeds.

http://www23.tomshardware.com

If you select "Farcry" as a benchmark, single core Athlon64
3700+ and up, beat anything Intel has to offer in a single core.
Gaming is the specialty of Athlon64.

If you select "Mainconcept Encoder", the Athlon64 4000+ does
about as well as a 3.4GHz Prescott, meaning the Athlon64 fell
behind by about 600MHz equivalent. You can see a similar trend
with "Media Encoder Streaming".

It means you really have to decide if your computer is for
"work" or for "play". Also, price will play a big part in
your decision, and you can take the performance numbers from
Tomshardware, plus pricing from a site like Newegg, to make
a "bang for the buck" chart for yourself. AMD 4000+ (2.4GHz) is
$368 US on the Newegg site. An FX-57 (2.8GHz) is $1011 US.
A P4 670 (3.8GHz/FSB800) is $636.

Now, the problem with the Intel side at Asus, is PCI Express
has replaced AGP on motherboards. If you go through the
list here (using this site as others don't have the list
any more):

http://nl.asus.com/products/mb/mbindex.htm

This motherboard has LGA775 socket and AGP video. It is similar
in vintage to your current motherboard, only has LGA775 instead
of S478.

http://nl.asus.com/products/mb/socket775/p5p800/overview.htm

The 915/925 and 945/955 generation boards are all PCI Express.
The only way to get a more recent board than the P5P800, is
to drop your AGP video card.

On the Athlon64 side, at least you have the A8V Deluxe for your
AGP card, and you get to reuse any DDR400 memory. If you plug
A8V Deluxe in here, you'll notice that it even supports dual
core S939 processors.

http://support.asus.com/cpusupport/cpusupport.aspx?SLanguage=en-us

At least for the time being, the A8V Deluxe is still a good
choice.

To have more choices for motherboard solutions, you'd likely
have to dump the AGP video card.

There is one other solution in the wings. There is a bridge
board, that converts a PCI Express x16 slot to an AGP slot.
The problem with this concept, is you can only plug low
profile AGP cards into the converter, and obviously any
decent AGP card worth keeping is going to be a full size
card. If you could cut a hole in the side of the computer
case, so the video card would have room, then an adapter
card like that would open up a lot more PCI Express motherboards
as solutions. (The adapter uses something like the Nvidia
HSI chip, but I've lost the URL I had to the announcement.)
Other than using an adapter like that, it is really time
to fork out more money for a new video card.

wow that's allot of info thanks took awhile .I think I will stick with my
current setup and change the 3.2 Prescott to a 3.2 extreme can sell mine and
new will cost only 300 different and can make half that back on the old case
and a Soya board.can you tell me does the extreme run hotter or the same
then the Prescott and I want to put on a xp120 cooler with nexus 120
silencer fan.
 
plus Paul do feel the extreme will be faster then the Prescott to pay the
difference.thanks

I think I'm losing track of the motherboards here. The P4C800-E
is S478, and you might have a processor like this one.

3.2Ghz (L2 1MB) 90nm 89 watts power Prescott S478
http://processorfinder.intel.com/scripts/details.asp?sSpec=SL7KC

The 3.2GHz Extreme Edition is S478. Power is just a bit higher.

3.2EE (L2 512KB L3 2MB) 0.13u 92.1 watts power P4EE S478
http://processorfinder.intel.com/scripts/details.asp?sSpec=SL7AA

I would say from a power perspective, they are in the same ballpark.

Is the Soyo board a S478 as well, or is it LGA775 ?

*******
OK. Look at the "Farcry" benchmark first.
http://www23.tomshardware.com/index.html?modelx=33&model1=64&model2=18&chart=25

P4 3.2EE Prestonia (L2 512KB L3 2MB) 168FPS (10% better)
P4 3.2E Prescott (L2 1MB) 152FPS

Now, "Quake III Team Arena"

P4 3.2EE Prestonia (L2 512KB L3 2MB) 235.5FPS (12% better)
P4 3.2E Prescott (L2 1MB) 209.4FPS

"Mainconcept Encoder" Benchmark

P4 3.2EE Prestonia (L2 512KB L3 2MB) 255 seconds (only slightly faster)
P4 3.2E Prescott (L2 1MB) 258 seconds

"Media Encoder Streaming" Benchmark

P4 3.2EE Prestonia (L2 512KB L3 2MB) 241 seconds (only slightly faster)
P4 3.2E Prescott (L2 1MB) 247 seconds

It looks like the Extreme Edition helps a bit with games,
but not with encoding.

Wouldn't it be cheaper to just overclock your current
processor by 10% ?

the Soya board is a 478 as well all are new retail SY-P4I865PE Plus DRAGON
2 (Prescott-Ready)
I got it and 3.2 extreme (still 1400 here)60 gig harddrive and 1 pc3200 256
ram for 550 canadian total and have my 3.2 Prescott sold for 200 .and can
still sell the board ,ram ,harddrive ,and xblade case.which board would you
use the Soya or the p4c800-e deluxe thanks .

The P4C800-E uses 875P Northbridge.
The Soyo SY-P4I865PE uses 865PE Northbridge.

The Northbridge chips are made from the same silicon die, only
a different package is used to hold the die. Intel sorts the
chips, and the fastest ones, with certain performance guarantees
on the DDR memory interface, become the 875P. The 865PE are the
next slowest chips, and the 848P (a single channel version) is
made from the remainder.

When Intel started shipping 875P and 865PE, at first the chips
had identical performance. Intel then applied the speed sorting in
ernest, and now there is a detectable difference between the
865PE and the 875P. (This is why some people in the overclocking
forums were looking for 865PE based boards, with early date
codes, as the first 865PE motherboards shipped, behaved more
like 875P.)

These differences are only apparent if you overclock. If you
are running at stock speed, both chips are designed for FSB800
and DDR400 memory. The 875P supports PAT, which is a shortening
of the register path in the memory interface. Intel is somehow
able to guarantee that PAT will work on the 875P, but I don't know
what method they would use to do that.

The 875P also has an extra, private interface on it, suitable
for connecting a Gigabit ethernet chip. The P4C800-E includes
that chip. If you were building a server, you might get improved
performance, as the Gigabit ethernet chip could run at full
speed while delivering data. Now, some OSes cannot make use of
this (for example, my Win2K install can only manage 300 megabits
per second, on a Gigabit link).

So, there are subtle differences between the two boards you
quote, but those differences won't be apparent unless you
overclock. 865PE boards tend to have video artifacts when
you overclock an FSB800 processor to about FSB1000 or so.
The P4C800-E has been pushed to FSB1200 without problems.
There is some issue with the clockgen above FSB1200, but I
don't recollect exactly what the symptoms are.

There is nothing wrong with 865PE boards - it is just, if you
have both an 875P and an 865PE, keep the 875P.

HTH,
Paul
 
thanks for all the info I will use the asus and sell the soya and go with
the extreme cpu.it has to be better the then the Prescott other wise it
would not sell for so much more.even if it runs cooler that would be a plus.
