when I played WoW (deployed now so cant) I played it on my P4 3ghz system that had an FX5500 256mb card and 2gb of ram, it ran it no problems at all at high res. I also had DSL too, never had any problems on any raids. I had some problems in Ironforge, but that was when I only had 1gb of ram, upgrading to 2gb fixed the problems there.
