Adobe CS needs ram, and planety of it. At least 512MB, although I would recommend more.
You mention 2.0 GHz minimum, but as mentioned before GHz doesn't really mean much anymore... although I would go with an AMD 2800+ minimum, there is so little price difference between those and the slower models that it's not really worth saving a couple of bucks there.
