Hi there, I currently own a P4 3.0 ghz and would like to know what sort of increase, if any, will I notice if i upgrade to a new dual core....I am running FS9 and generally keep the scenery to dense to minimize the hit....I am more concerned wit a fluid simularion vs eye candy and would like some feedback as to what sort of increses i can expect to see....thanks!

I think you will see a a very noticeable difference. It would be a wise upgrade, just dont make the mistake I made buying an amd dual core cpu. Go with intel.
