Ok, tested with all five in Dalaran, instead of each instance of Wow using 390MB of memory, it was using 580MB. That's it. Sooo...I never went over 3.6GB of memory used with all five dancing in Dalaran during a peak evening period.

If you crank your graphics, you'll use more, one client on full will use 1-1.5GB of memory, but that's on FULL settings at full res. If that's how you run things, you need gobs of RAM. If you run smaller child instances, you simply do not. 4GB is fine for 5 clients, 4 on low.
This strange and not what I get at all. Are you running 2 screens ?
I am running quite good now thanks to the advise given by you all. Still using the 9600GT and my 4MB of ram (until the new arrive).
I played around with the performance window and set 2 wow on the last 2 cores and 1 on the first 2
then I set the 2 slave windows on 20fsp using the wow comand.
The result is i'm getting 60fps on main now going down do about 40 sometimes, runs nice over all but still lagging in SW.
memory usage is always around the 3GB - 3.4GB (which is max since only 3338 is used from the 4GB)
CPU usage is about 40-60 now but all cores are running

so I think I will stick to my memory upgrade since i'm maxing it out still
