I got this pic here to show what does it show in my Device manager. It puzzled me, because I got one only, a 3 GHZ Intel P4 800 FSB etc...
I'm using a Win XP Pro and try the Tweaking Tool from Intel to make things easier for me...result is that does not aceppts the Intel software, cause it says is not compatible.
Any clues?

This is due to the hyperthreading technology which is simulating
dual cpu's! It's as it should be!
cheers

EDIT: I visited your gallery at renderosity, you've got skills man!

yup yup, that's right. hyperthreading! supercool. instead of dividing your tasks and processes in the software layer, p4 with HT does it in the hardware layer, so it is even faster and less heavy to go mulitasking!!!

so don't worry and don't go all happy cause they didn't make a mistake at the shop and give you two processors for the price of one, i'm sorry hehe

I don't believe they won't make such difference, hyper threading or not. I've got a P4 3.00Ghz and i've switched HT on and off to see if it differs, but it's not such big difference. <dream mode>Wow, how would it be to have a REAL 10 CPU computer. </dream mode>

amd has the amd 64 which is 64-bit processer which would be the equivilant of a dual processing amd 2800. i think pentium has one too. but in the old days the best speed was dual processing motherboards with 2 processors running in tandum. these days they just combined them into one wallet emptying machine

Juts posting this to make sure that no one gets the wrong idea...

Hyperthreading doesn't really make the computer run two processes at the same time. That is impossible as long as there is only one CPU core. Hyperthreadining almost does it.

for a Desktop you dont want 2 CPU's !!!! this would be a waste of money in many cases.

for example, take Unreal TOurnament 2004.
this game only uses 2 processor threads, one which runs the sound,, (very light on CPU power) and the other does everything else.

therefore... a Single 2Ghz Pentium4 system would out-perform a dual 1.8Ghz Pentium4 system (in theory)

leave multiple CPU systems to the serversand cluster networks.

qwijibow is right, 2 cpu for home is too much, beside if you have 2 processor, with windows solitare, or word you are not going to see too much difference, however with heavy programs adapted for the double processing, like 3dmax, lightwave, Premiere, Photoshop, etc. you can see the difference.
For all intel lovers, aparently amd will kick a**, check this new configuration AMD Opteron Four Way

not dual .... 4 Way

I think multi-core will the future but instead of build a Bi-proc sys is better to create for me a clustering network..like this
http://openmosix.sourceforge.net/

I'll try in the next day, with 2 or 3 on lan PC, if someone have already tried it...I accept any advice

Try setting up a linux cluster with distributed processing. You can setup your dream 10 cpu system using 10 different computers connected over the network, this way...
