I've been running my 850w Cooler Master Real Power Pro for about 5 years now, and I'm looking to upgrade and want a PSU to carry me another 5 years if possible. Fortunately CPUs and GPUs have undergone substantial die shrinks the last 5 years resulting in a decrease in power. But I want to make my PSU purchase as future proof as possible. So I'm deciding on a Seasonic, but am having a hard time deciding on the 1000w Platinum or the 1250w gold.
The 1000w Platinum received the best review I've seen yet at jonnyguru:

The 1250w Gold faires well in tests, but sometimes was only on par with Silver rating (note review is of XFX 1250w Gold, which is the Seasonic 1250w Gold rebrand):

The question is, will the 250w extra provided by the Gold unit be worth it over the similarly priced 1000w Platinum unit?
And feel free to point me in a completely different direction if you want. Thanks all!

Thanks for all the great comments so far. Obviously with this kind of investment, I've been doing a lot of research and reading up on a lot of PSUs. I've got another one added to my list.

Now, this unit did have some trouble hitting Platinum on my load testing gear. This could be because I don't work to stabilize incoming line voltage on purpose, but it really doesn't matter. When you take into account the error tolerance of my power meter, it does pass Platinum.

http://www.newegg.com/Product/Product.aspx?Item=N82E16817151105so... how do we score something clearly designed by wizards to completely wipe out the competition? Easy. I'll take away points as usual. From a perfect score, I find myself having to take away half a point for ripple suppression. It was real good, but not the best ever. But... I have never seen a unit average better than 0.5% regulation, either. I'm going to do something I rarely do. I'm going to put that half point back on. This is as close to the perfect power supply we're going to get, people. 10

Finally, after removing three more screws, I can separate the rest of the housing from the PCB. And there we have our Seasonic X-Series based power supply in all its glory.

Perfect voltage regulation? Check. Survived crossloads? Check. Decent ripple suppression? Check. Rise time within spec and minimal overshoot? Check. Efficient? Yes, but NOT 80 Plus Gold. I'm giving this unit a performance score of 9.5

I've seen stability like this before, folks, but seldom on a unit this size. The 12V rail, which sees nearly a 74A difference between tests one and five, is still managing to get away with 1% or better voltage regulation. That's quite an accomplishment for any unit.

It's fully modular, has that nice flat black cabling to help with cluttered cases, and has enough peripheral connectors to satisfy almost everyone. Going to have to do 9.5
