Need a new PSU, but which one?

Hi, I recently upgraded my PC but I'm maxing out what my current PSU can handle Under high loads the PC shuts off which isn't a surprise since it sometimes pulls 850W from the wall.
I've not even had chance to properly OC my 5970 yet so I'm after a 1kW PSU but there's too many to choose from.
The two I like most are the Enermax Revolution85+ 1050W (and the 1250W version since its only £25 more) and the Corsair 1000W.
Which, if any would you go for?

My rig is in my sig. i7 is at 4Ghz (~200W) 5870 OCed (~200W+) 5970 OCed (~300W+) then there's all the other components and fans etc so it soon adds up.

I've decided to go for the Corsair 1000W. It has longer cables, is £50 cheaper and has a five year warrenty. Was reading through the Enermax support forums and X58 chipset compatibility seems a bit hit and miss and I don't want to take that gamble even though I really like the Enermax.
