I wish to add something here IF you are attempting to run a single machine and multiple copies of wow your lag will moslty come from hard drive load times specially in cities

i would suggest adding at least 5 hard drives to the machine for a lot better performance 2 raids <stripe> for better performance if just to run 4 wow clients on,

and a single drive for operating system and 1 wow client

as most of you will notice that when your lagging bad your hard drive will be running off the planet.

hope this helps
I run all my wow's from the same harddrive, same installation folder with minimal problems like you're describing. I think the money would be better spent elsewhere on the system like high-grade ram, quadcore processor, or a high-memory graphics card. I can't emphasize the performance boost I experienced when I reduced bit sample size from 24 to 16 on all clients. Pretty much ended all of my lagging out issues where my system would bog down after a few hours of playtime.
