ok, so the cheapest way is to buy a new PC with atleast a Dual core processor? and atleast 3 GB RAM? and then I could probably get a vid card seperate... Now, wheres the cheapest place to look? And what price range should I be in?

EDIT: I found this:

Is this a good deal for it? Or can I get the same specs for cheaper?
