Hello I recently bought a brand new pc for the second time, i could nt able to upgrade my old one which i bought in 1996. Im a web developer and 3d animation specialist,Now my new system is perfectly working. I used to work in Maya 3d software, when I try to render the animation, still im not satisfied with the speed its ok for novice users but i have plenty of jobs to do in animation so i need a faster rendering processor, I want to know the difference between core 2 duo and quadcore processor, some say quadcore processor increase the speed by 4 times,core 2 duo processor increase by 2 times, i want to know the exact difference between the two processor.
