You systems is scoring very high.
IMO, with current technlogy a 2.4 ghz dual core or quad core system is really a sweet spot in the technology curve. These systems can be purchased for $400 to $500. While one can invest more money and beat the performance by 25% it's not really enough to notice in day to day operation for most people.
My rule of thumb is to upgrade when performance can be doubled (200%). For me, anything short of that is hard to notice. As far as I know, it's impossible to double the performance of a $400 2.4 ghz machine with current readily available technology.
In a couple of years Photoshop should be able to leverage multicores and change the performance curve but Adobe has said it's going to be a ways off before they do that.
(I'm speaking of a photoshop machine. There are some multicore machines that can do video rendering where the speed improvements would offer a worthwhile payback.)
