dual processor systems

Hi guys

Last weekend I checked at my apple-store and they had this 22inch lcd.. Oh my... I felt in love! I am willing to pay everything they want. Unfortunatly that cute thing doesn't work with my P4 2,8GHz System (at least not compatible to the DVI-Interface of mine).
And it doesn't make sense to plug my ibook to that beautiful thing (running 1024 res... ,-))

Now I would like to buy an apple system. But I just don't know, if there is an overall performance improvement of those dual systems (powerpcs). Is it dependant on the software, or does macosx kinda simulate a single processor system, so that the applications don't have to support dual processors?

And if it's an overall improvement, how much is the effective improvement? more than 90% compared to a single proc machine?

And is it easily possible to upgrade Raid and Graphiccard on those powerpcs? So that I could go for the cheapest and later on upgrade...

tnx!!!

Cheers

Well, Mac OS X itself will use both processors properly, and many apps are doing so now. I believe Photoshop 7 uses them both. Well, think of it this way, in the apps that DO use them both, a 1ghz dual will be equivalent to a 2ghz single.

And besides. The single 700mhz in my iMac handles complex stuff REALLY easy, and that's a really slow chip compared to them!
 
tnx Hypernate!

So, what is usefull? I am no heavy video and graphics freak, but on the other hand I use many 3d-progs such as VMD (3d-protein visualisation prog).
And I love nice 3d-games...

I was working on a dual 867Mhz powerpc and it was a dream!
For my taste standard operations such as office progs, video-playback and internetbrowsing should work fast.
And what I am used is the speed of ibooks G3 600. This is too slow for me.. Good enough for a mobile system, but not for a desktop-system.

Now, is a single CPU such as the G4 800 good enough for this work or do I just have to go for a dual powerpc?
If a single CPU is good enough, is it possible to change the graphic card on those single CPU pcs (imac)?
Unfortunatly the GF4 Titanium is just available on the powerpc machines (as far as I know). And I love to have it's performance and the option for a second screen such as the 22inch lcd.. ,-)

Sorry for bothering you guys with such low-level questions.

Cheers

Buy the best system you can afford. Dual processors *are* worth paying extra for, IMHO. Everything runs a little smoother, even if it is only the OS that is coded for MP.
