1x Mage prepping for Cata

[Kawasa]

nom nom nom gbank.

Oh... I thought the cores were CPUs themselves.
So does quad core means 4 core and duo core means 2 core?
I hear people around me just say duocore or quadcore.
What is 2coreQuad?

So how much ram do you suggest to get the video cards?
And is going quadcore or whatever its called (2corequad?) going to skimp out my high detailed fun in Cata?

Opened to other suggestions that will aid my epic pewpewing in Cata.
