First PC Build - Opinions/Help

[Guest]

I'm currently in the last stages of the parts choosing for my first Gaming PC.
I will list below all the specification for the PC, and links to the purchasing page for prices, and Manufacturers page for specifications on each part. In this Thread, I would like you opinion on the build, be honest, but keep it normal please. And some help on compatibility between parts. To be more specific, I would like to know the following:

-Will My CPU, drag down the GPU at all? and will it drag it down more if it has CrossFire?
-Are all the parts compatible?
