Best PSU for my system?

[Jamieward]

Hey guys, my Corsair HX 1000 just died after 2 years....
Anyway, I'm looking for a new solid PSU, I'm running 1 SSD, 1 HDD, 1 DVD drive, 1 AMD 6970, on a z68 board with an i5 2500k.
I went crazy last time, there was never a need for a 1000 PSU, I thought if I bought big it would last longer. Obviously I was wrong.
What would be a smart reliable/quiet PSU for my rig?

I was looking at the Corsair TX range, do you know what makes the AX so much more expensive? I see the bronze and gold ratings, but I don't really get it.

Efficiency ratings is all.
