power supply is lack luster because of it's efficiency. It only has 70%.

I would go with 700/750watts for 2 graphics cards that level.

Here's a 750w. http://www.arc.com.au/pub.php?pid=38890&p=product

Your build looks good. Agree with Baz, if you plan to xfire or sli buy the better psu now instead of purchasing later
