Agree,latest Total War :Empire- system rquirements are the same as for
HOI III.(1 GB XP, 2GB Vista, 256 mg graphic card).
Though I believe Total War eats RAM for graphical presentation more than processing game core variables,oposite to HOI III.That means that Total War hardly will benefit from 4 GB RAM,while I believe HOI III will benefit.
Sounds about right, Unfortunately I have 3GB ram, a 512mb Card but 1gb of the ram is shared with the card. I would switch it off but I don't even trust myself to go there. Plus it can be an advantage in some graphical intense games.
