Photoshop CS3 down to crawl speed

After working in Photoshop for about 2 hours, everything slows down.
I just tried to use the quick selection tool on a small 5mb file. It took 5 to 7 seconds, and I had to look at the watch. When I change the view percentage, I get the tiling, opening a 250Mb image can take up to 30sec (a layered Tiff file).
I have a white 24" iMac with 3Gb RAM, 2 Gb RAM for Photoshop (so a recommendation I got from a book).
Activity monitor: CPU useage goes up to 90% with 1Gb real memory during selection process with quick selection tool, . 15threads, virtual memory 1,9 Gb in Photoshop alone.
Weird thing: when I watch the ants of the selection march, CPU percentage changes, between 20 and 35% even when I do nothing, and then - suddenly it shot up to 95% (still in the Photoshop department) for a moment, even though I wasn't doing anything.
Bridge: 113mb real memory, 800mb virtual memory.
Free disc space 28Gb.
I can't see anything on the activity monitor that explains the slowdown.
iTunes was running, and is now stopped in the background. I have a weird feeling that iTunes is responsible for some reason. It only starts when I open iTunes while working.
But I could be wrong.
Could it be what's called a "memory leak"?

Looks like nobody else has noticed this...

If it was a memory leak I guess a restart would fix it. Then I think 28 GB is enough free disc space how to be worried about it. As for iTunes I don't use it so I can't say I had to blame it. Sorry.

Repair permissions? Failing that reinstall the software?

repairing permissions does nothing. Back in 10.0 and 10.1 it was needed now, its more myth then fact.

What exactly to you mean?
I am on CS3, which is in version 10.0.1. I just checked the updates available, and there aren't any.
The strangest thing of all this slowdown is that it only happens after several hours of Photoshop work, probably after 4 hours.
Could Bridge be involved in this? Bridge CS3 is not the most reliable application, which is why I just bought Expression Media 2 (the former iView Media Pro).

By 10.0 and 10.1 Maflynn means the early versions of OS X 
What else is using RAM up? InDesign munches RAM up.

I don't have InDesign. When I work in Photoshop I usually have Bridge open ( I posted its RAM/disc useage above), iTunes for the mood, that's it. RAW processors I usually close.
I checked the activity monitor while performing tasks. I perceived sudden bursts of CPU useage by rather simple tasks like the "marching ants".
If you have iTunes on - could it block a whole core (I only have two here)?
What is really weird is that this only happens after hours of Photoshop work (4 hours, or more).
