i'm tired of everyone asking should they go to quad core.
Here is my answer
Quad core is a waist of money right now, we don't have any need for it. quad core was developed for server use. it was designed to be able to run a massive ammount of programs at once.
I think the common misconseption is that if you have quad core it will be alot faster. but that is not really true. it isn't any faster, it can just run more things at a time. they still run at equal clock speeds, the quad core just has the equivalant of 4. for example, just because you have a 2GHz quad core CPU doesn't mean that you have 8GHz. you just have 4 2GHz.
I have an intel 2.66GHz dual core, 4GB of RAM and i run dual 19" widescreens, i can open every program on my computer, and my ram will fill up long before my CPU will bog down.
So for those of you out there who want a quad core so bad you can taste it. don't waist your money trying to show off, go buy something usefull, like dual Nvidia 8800 GTX's, or a USB beverage cooler. lol
