People use 1200w psu's when they build systems that require big power.An example would be 3 580's on a OC'ed I7.

Get the 1200w and keep it for future builds just like people that buy $500+ cases.

A 1200W unit would be suitable for like heavily OC'd quad-SLI 580's with water cooling.

You don't need anything remotely like that for what you're proposing (2x6970). 750-850W is going to be perfect. You might even be able to run a 3rd 6970 on a high quality 850W unit.

Although there's something to be said for 'going big', the fact is, something like a 1200W PSU is not likely to be nearly as efficient at a lower power draw (like desktop usage) as one that's properly spec'd to your rig.

Might want to have a peak at this unit, which I started a thread about here in the PSU forum about an hour ago. It's really about perfect for what you're planning here, and a CRAZY good deal right now.
