Under optimal conditions, I think the C3D may well have 10 times the computing power of that system. This assumes a perfectly multi-threaded application making use of advanced SSE capabilities if available - like 3d rendering.

Even in an application that isn't multi-threaded, that will be the case. Try to compare the 23-24 seconds that an E4500 uses to calculate a 1M test in SuperPI, against whatever a P3 @ 500mHz uses, it will be less than a tenth. And SuperPI is neither multi-threaded nor does it use advanced SSE - it was developed in 1996.

It does, however, use a fair amount of memory, and on a modern CPU, it probably fits within the cache (or a large portion gets placed in cache), whilst the older processors with smaller caches will struggle. Memory and related controller logic being 4x or so faster (peak speed) will also help a fair bit. And yes, of course, the processor running about 4x the clock-speed will also be beneficial.

They have a Quad there for 599 Euros without monitor. But comes with 2Gb Ram only and an onboard graphics card. I think its perhaps too much anyways since I plan on using only XP on it and later migrate to Linux.
To be honest I'm more excited about the Thinkpad. Ever since CornedBee mentioned it, it got stuck in the back of my head. I had heard good remarks about them before. But my immediate search revealed, as I said a few posts down, they are poorly represented in Portugal. But after getting annoyed at Asus and Toshiba, I decided "what the heck". Ordered it from the web today. It will take maybe 14 days to get here. And they are black!
I'm going to get the desktop later today at around 8pm. I'm not going to risk getting annoyed again (because of that SATA drive) so I went the extra mile and decided to add a 160GB PATA from a local store. First I'll see if SATA is native or I can boot from an USB stick in which case I will install the SATA drivers on the stick (the desktop comes with no floppy drive). If both fail, I'll drive there quickly and get the PATA drive.
You'd think a C2D ready mobo can boot from USB?

What motherboard is it? Shouldn't take more than a couple of minutes to figure out...
Oh now that's just racism!And they are black!
Edit - Matsp:
All valid points, i do however believe that the performance jump will easily be 10 times, still. My new machine is atleast 4 times faster than my old Celeron D, and that one is still considerably faster than an old P3...

I don't know, bleh. I saw Asrock on the chipset on a picture in the box. I'm ridiculous, I know...

I think it was this one or something very similar. The image is almost a look-a-like.

I know I'm behaving like a kid, but these things have changed so much. I can't recognize half the new acronyms, abbreviations and terms...
Anyways, is it what they call "Ready-to-Use" USB ports?
EDIT: Ok. Nevermind. I think I got it. The manual speaks of user togable legacy USB support, which is I think what I need in order to have it available prior to the OS installation.

I might be a little late but the E4xxx series is getting a bit old and is being replaced by the E7xxx series. The E7200, which has the same release price of a E4500, has a higher frequency, SSE4.1 support, more L2 cache, higher front side bus and may be a bit more energy efficient since it's a 45nm chips vs 65nm. The performance difference isn't huge between those two, but the E7200 is leading. Of course, this kind of information is more interesting if you buy your parts by yourself than if you buy a pre-assembled system.
As for the SuperPi calculation time (1M digits) between a C2D vs a P3, here's some results on my own computers:
- C2D (3.0 GHz, 6MB L2): 15 sec
- P3 (1.0 GHz, 256KB L2): 2 min 25 sec
The first system is 1 month-old and the second is... near to 9 years old.
I hate real numbers.
10x faster. Quiet accurate the predictions in the past posts.
Meanwhile yes, I could see E7xxx's. But precisely as you said it, being pre-assembled I couldn't get quiet the optimal configuration. If I remember correctly these machines where being sold as part of more featured-rich systems, consequently more expensive. And that just doesn't fit with the usage I want to give to this desktop.

Ok, I found all I need. To wrap it up (and thanks a bunch to everyone who posted. You people are awesome. Even though we may disagree on other issues, I love this little corner of the web and couldn't make it without you)
- All AsRock boards support boot from USB device, which basically guarantees I can load the SATA drivers from a USB stick during XP installation.
- More important though... AsRock boards have this:
Attachment 8199
Which, if it means what it seems to me, I will not even need to worry about the drivers.

If some people are still interested, here's one article I remember reading, where they compare some of the C2D processors from different series.

I am thanks. I'm suddenly gaining a renewed interest in these matters.
