Can I run two 6950s in Crossfire on a 750w PSU?

[Nitemare15]

I just home built a system. In retrospect I should have gotten the 950w PSU from PC Power and Cooling, but I'm not sure if it is needed. Currently I'm running 2 x Spinpoint HDDs, a Corsair 60GB SSD, an OCed 2500k @ 4.5GHz with a VCore of 1315, a Gigabyte Z68 mobo, two sticks of 4GB Gigabyte DDR3 1600 and one MSI 6950 Gigabyte Twin Frozr III at stock settings (may OC to 900 with a voltage of 1200). My question is, can I run one more MSI 6950 Gigabyte Twin Frozr III without upgrading my PSU to more than 750w?

Yes you can if it is a quality PSU, here a few cards compared total system power http://www.anandtech.com/show/4239/nvidias-geforce-gtx-590-duking-it-out-for-the-single-card-king/16

Oh cool. It's a PC Power and Cooling 750w Silver Cert. Is that going to cut it?
