Biggest differences between a 1500W & 1200W system?

So after looking at the [H] reviews of the SilverStone's Strider 1500W (SST-ST1500) and the Antec High Current Pro 1200W (HCP-1200). Both seem like pretty good & beefy PSUs for a high end build. I have 2 questions.

I know the Antec PSU has a longer warranty. And the Silverstone has 300 extra Watts (and an $80 price premium).

1. Other than these things, are there any other major differences between these PSUs that would affect your buying choice?

2. Is it likely possible that even for most "high end" builds, these PSUs might be overkill/waste? What type of system would a 1500W PSU handle that a 1200W system could not? Any examples?
 
I couldn't think of any semi realistic system build that would require that much power. Running 4x GTX480 or something?
 
Multiple fermi graphics cards, tons of hard disks, mad CPU OC, running water cooling pump and tons of fans, possibly decorative lighting fixtures, and don't forget epeen.
 
You would have to get pretty extravagant to see a difference between the two.

4x GTX480 would be about 1000W, if you had them in a dual socket system with two overclocked i7 980X chips you could break 1200W.

I think that if you had 3x GTX480 the 1500W psu would be close to its 50% load that is ideal for efficiency while the 1200w would be a bit beyond it. Although I'm not sure how much you are going to care about efficiency if you are building a rig like that.

the hcp1200 has a claimed 1700 continues output but was rated at 1200 because of some switch issues the same reason the st1500 doesn have a power switch

That is incorrect. The switch has nothing to do with it.
