How many and what size powerheads do you recommend for a 65 gallon tank?

I just built a new stand to accomodate a refugium underneath and will be switching over soon (which will be a huge project in itself). But, I would like to update my powerheads when I do this. I do have corals, mostly polyps, mushrooms, favia, frogspawn, etc.
So - I have a ReaSea wavemaker pro and currently have 4 Maxijets hooked up which are starting to sound pretty bad. I wanted to replace them with the Hydor Koralia Evolutions. My question is - what size do I get?
Here are the specs from the website. I was thinking 4 750's...is this too much flow though?

A lot depends on the flow your trying to achieve inside the DT.....There are tons of things that will dictate flow and flow needs and your biggest being your rock layout.....That is what hinders most with achieving good flow through the DT.....What kind of corals you currently have, and what your intentions of keeping as well......But all in all I would plan more flow than what you think, because as things grow in and tank fills the flow will be cut. Better to have more than not enough.....Extra flow can always be slowed down or such till it's fully needed.....
