P '4' or P'D' Processor

On the Dell site the options for Processors are numerious. Is it simply as the price goes up the better the processor.
On the 9150 model I'm trying to decide between :
Pentium D 820(2.8GHz,800FSB, 2x1MB Cache)
or for an extra £47 the :
Pentium 4 650(3.4GHz,800FSB, 2MB Cache). This will be used with 2048MB Duel Channel DDR2 533MHz(4x512)special offer 2gig of the price of 1gig. with a 250GB hard drive(7200rpm)ATA.

The other model Dell 5150 has a
P4 640 with HT(3.2GHz,800MHzFSB,2MB Cache). This will be used with 2048MB Duel Channel DDR2 400MHz(2x1024)special offer 2gig of the price of 1gig. with a 320GB hard drive(7200rpm)SATA.
Is there an advantage of having 2x1024 as against 4x512MB and will I see the difference from DDR2 at 400MHz to 500MHz

Well, my main desktop is a 640 - like that 5150 model - and its speed amazes me during web design, video editing and music creation.

If you're thinking of the 9150, I would probably plump for the Pentium D - not so much because it will be a lot quicker, but because it is cheaper and will be quicker to some extent with the right software (which is a little way down the line)

Memory modules - fewer modules can be better if you are dealing with large quantities of data. A video editor or CFD expert, for example, would rather have just two large modules so that fewer data gets split. It is not a big difference though. Of more importance is have some upgrade room without having to replace smaller modules, though with 2GB, that's probably not a major issue either!

I didn't spot your last question: 400mhz versus 533mhz.

I don't think that it would be a world of difference but it is inevitably going to produce some difference.

The less demanding your work, the less you will notice any of this. The converse is true as well.
