Video card match for an 8350 BE?

Would crossfired 7970's be significantly bottle necked by an 8350 BE paired with 16gb's of PC1866 memory?

Depends? What resolution will you be running at?

I usually use 1680 or 1900 depending on the game. I was also thinking about using multiple monitors.

I will go for AMD combination only.What PSU you have ?

I have a BFG 1200w power supply. I don't know the exact model.
