You'd want a higher watt psu unless you only plan on going with a low end GPU, not saying you need something silly like 1kw.
Would say go with the 550w version of the psu.

450 should be enough if its good quality. I'm running twin GTX660's an overclocked 3570k, three phyiscal hard drives, 10 fans, an SSD and a sound card inside my rig and although I run it off a 760w psu, I've never seen it pull more than 500w (I have a wattage meter on my desk and my PSU doesnt turn it's fan on until your pulling over 550w, I've never heard its fan turn on).
