Hello,
I am running an i7 920 o/c to 3.8 My mobo is an asus p67x58d premuim. I have a Corsair 750w psu. Would I have to upgrade my PSU to run 2x 560's, or 2x 6950's?

First, I admit right now I didn't look up the mobo. I am at work XD
But, make sure it has 2 PCI express ports, I am guessing the cards you mentioned are PCI express, I think they all are now a days.

Second, look at the cards you want to put in. A large number of cards require additional power, 6 or 8 pin connections. You'll need to open your case at look at the power connectors. See if it has any of the power connectors your new Video Cards will require.

Last, Check the specs and reviews of the cards if possible, some Video Cards will come with adapter's to make a standard 4 pin power connector to the correct power. Usually the 4 pin to 6/8 pin adapters that come with cards require two 4 pin power connections; look to see what one, if any, come with the card.

Once you get the Video Card info from the web, the actual physical check of the connections will take all of like 10 seconds.
