AMD Crossfire questions

[Dacalala]

Hello,
I am going to get a desktop with integrated graphics (AMD Radeon HD 7540D). Would I be able to perform Crossfire with the AMD Radeon HD 6670, or only the AMD Radeon HD 6570. And as my desktop has a lot of features for a solid price I do plan on sticking with it for know and then buying the extra graphics card In a bit.

Chipset: AMD A75
Processor: A6-5400K
By PSU (Sorry still new to computer specs and etc.) i think youre implying maximum power wattage?:
300W
And I'm not sure what you mean by cabin specs, but just in case
The desktop is:
Height 14.9"
Width 7.1"
Depth 15.8"
