Hi! I am thinking of getting a system upgrade and I wanted to know if there is a lor of notable differance when using Dual core & Quad core processors.

I mean I have an Intel dual core laptop which I cannot tell much differance with so is a quad core really much differant to a dual core?

The 2 particualar models I was looking at are the 4400+ Dual core and the 4800+ quad core processors.

Anyone had any experiance with the new quad cores?

Thanks
