Is it ok to buy them used of Ebay or is that a no no?
If it has 2-3 years of warranty left on it, I'd say go for it.

You can calculate the needed size of a PSU with http://extreme.outervision.com/psucalculatorlite.jsp
But remember: You want to run the PSU at 50% load to save energy. So if your PC needs 300 Watt, go with a 600 Watt PSU, especially if it's not a 80plus certified PSU. If you can go for a 80plus platinum PSU.

Efficiency drops by 4-5% at 100% load compared to 50% load, it's not worth paying extra for a 700W bronze unit just to run it at 50% load.
Would a Corsair TX850 Enthusiast Series V2 be to overkill? (I might add another GPU later)
For the same money you can get a Superflower 800W Golden Green, or Coolermaster Silent Pro Gold 800w.

It's a little dated but it should be enough for a 5970.
Even a 450W Seasonic G series/Rosewill Capstone 450 will do, but for peace of mind get the 550W version.
Would this work? http://www.ebay.com/itm/SeaSonic-SS-550HT-80plus-550W-ATX12V-EPS12V-Active-PFC-Power-Supply-for-Gaming-/251258747734?pt=PCA_UPS&hash=item3a80303b56&_uhb=1

So, I have bought myself 2x 5850's and I was wondering if one of these would do: http://www.gigabyte.com.au/products/product-page.aspx?pid=2796#kf (I know it's pushing it if at all but I have one on hand)
