Can these graphics cards use AMD Crossfire?

At the moment I have a Sapphire AMD Radeon HD 6670 1GB GDDR5 and an Nvidia Geforce 210 which I use to run extra screens. The 6670 runs in the PCI-E x16 port and the 210 in the PCI-E x4 slot. My brother just bought this and it is exactly the card I want.

I have 3 questions:
1) Can I have the HD7770 and HD6670 running together using Crossfire?
2) What's the difference between PCI-E x16 and x4?
3) Using the display port feature, how many screens will the HD7770 be able to support?

Thanks in advance,
Dan

Thanks for the reply.

Despite not being able to crossfire, do you think this setup would be feasible? would I be better buying the hd7770 and not using crossfire, or buying another hd6670 and crossfiring?

Thanks again,
Dan
