Default Need new 7970 for crossfire

I bought a Diamond 7970 reference card last year on sale. I have NZXT 750W HALE82 80 plus bronze psu, and my cpu is a i5 3570k running at 4.2ghz. Will my PSU be enough to run 2 7970 cards at stock speeds? Should I go for another reference model? I was planning on getting crysis 3 and bioshock infinite later on, but now they are being offer for free with amd cards. I do game on 5760x1080 and feel the need to max everything on this setup. Dont like having to play BF3 online on low settings to maintain 60 frames in eyeinfinity. Will my PSU be enough to power them? PLZ help.

That PSU is enough. Overclocking will push it, but at stock, more than enough.

What is the best cheapest 7970 to get from newegg? I want to stay at stock speeds, dont want to go over 750watts. Will two 7970 be enough for next gen if I ever decide to go back to one monitor? I would like to keep them for 3 years if its possible.

That PSU is fine. You could get an HD7970 1Ghz from Gigabyte for $380. It's superior to a reference cooler and 1Ghz means a bit more speed since you don't intend to overclock.
