How are/were you running 5 with 2GB? I just finished loading 4 to test my machine (which has 2GB of memory) and I'm sitting at around 90-95% memory usage and I've gone through and tweaked vista, stopped unnecessary process', etc.

edit: Nevrmind, read your post wrong. Does anyone know if it's even possible to run 5 with 2GB? My main seems to max at around 350mb with three alts sitting at just less than 200mb
