^ Most people have only used a dual core processor in their computers; Athlon X2 or Core2Duo. When you switch from those to a Quad-Core Processor, there is a HUGE difference with how much it can handle being asked to do. -Like an LS7 for your computer. To top the Quad cores, AMD is releasing a SIX CORE Phenom 2 series processor this month. 0_o Some are already out, and server chips have been out.
My laptop is an Athlon X2 and it can only handle so much. My big computer on the other hand.... . good god..
The new graphics cards (video) out now are getting such high frames per seconds ratings that if things advance any further, the human eye is the weak part in that it can no longer differentiate the frame rate difference.
