Any ideas on a PSU for running Xfired 4870x2's?

I am uncertain if a PCP&C 750 will be enough to run both of these cards, along with 2-3 HDs, 2 DVD drives, and an OCed E8400 @4 ghz.

Do I need to start thinking about 850 watts or more?

That's a quad cf? Absolutely not. 750w won't be enough. Brands doesn't matter at this point, it falls far too short. 850w likely won't either. It'll probably be in the 1000w range.
