can u please explain to me what a quadro core means?? hmmmm so sorry im so dumb at this..

I'll replace the term [i]quad-core[/i] to [i]multi-core[/i], since the latter was replaced to avoid confusion.
Another definition:
The term [b]multi-core[/b] has four CPUs working together on a single chip (in this case, Intel's Core Duo and AMD's Athlon X2), while [b]dual-core[/b] has two seperate CPUs working together.
There are software programs that require high-end CPUs for performance.
I'll give you an example of what I mean: There are 4 processes, and each process has its own purpose. And there are two kinds of CPUs, the multi-core and dual core.
In a dual-core CPU, [b]only[/b] two running processes are allowed to be executed. But, what if you have four? Since each CPU core can handle a single process execution, the CPU can be slow if there are more data to be executed seperately.
On the multi-core CPU, four running processes are executed simultaneously. Since there are two or more CPU cores embedded, and each can handle a single process, there is no signs of slowing down when handling large amounts of data.
