Indeed. A high quality 400w PSU or so should be fine, btw.
Things is, most people do *not* have a quality PSU. So "550w" often equates to around 300-400 "real watts" (i.e., amps on the 12v rails). At best. And then it will also be less efficient, reliable, cool, and long-lived, as a rule.
A 5770 should tear through Oblivion without breaking stride (not to mention that it's extremely power efficient). A C2D is perfectly OK as a CPU too, and again doesn't draw much.
Anyway, I would have to agree that RAEVWD plus BC is likely to be the culprit.
edit: And you might find using PyFFIed meshes, as well as making sure you have all the latest updates for *all* mods, and have QTP3 Redimized rather than "full" could all contribute positively, somewhat.
