You can handle 6970's, so yes it is overkill for 6870's.

2x 6950s in crossfire draws ~329 watts.... Throw in ~200 for your CPU and the rest of your gear and you are well under 750 watts man. You will be fine.

Just search around the net for benchmarks of your cards and look at the "power consumption" page that most all review have.

http://www.guru3d.com/articles_pages/geforce_gtx_670_2_and_3way_sli_review,4.html
^^ This is a 670 review but has a chart of cards to compare against

Keep in mind that the numbers are usually the entire system, not just the cards. So that is why I say you will be totally ok with a 750watt PS

eBay or wait until something pops up on OCN marketplace. I checked Newegg, no open box/refurb/etc for 6K series GPU's.
