With 4 gigs of memory I'm betting anytime the wow client goes over 500 megs yer gonna get a ton of lag.

Ideally vista needs 2 gigs of memory for itself to run without paging any thing out that leave 2 gigs free for the game.
I got vista 32 with 4gigs of memory(3.2) and the only places i got issues is dalaran and shatrath but ofc i experience long loading screens when i load 4 clients into WG! I even quested about every place as a 5 boxer and done most of the instance and still its only Dalaran and Shatrath that causes issues.
