I5 3570 with AMD 7950, PSU suggestions?

[LemonCakes]

I am thinking of upgrading my Current PC and making the big switch over from AMD's piledriver CPU's to the Intel Ivy Bridge CPU's, specifically from the FX 4100 to the core i5 3570, i'm also upgrading my GPU to a 7950 from a GTX 560 oc, however, I need suggestions on a power supply; should I go for the 600W corsair CX, as I have been lead to believe that intel's new 22nm architecture is extremely energy efficient, or should I go for the more expensive 700W power supply, just to play it safe?

You can buy this but if you find the 450W version, even better. It's a really good psu, modular, gold certification, 5 warranty and the price is really good.
You don't need more than that. Just make sure a good psu and 450W should be enough.

Thanks for the suggestion, also if you wouldn't mind, could you read through my upgrade specs, just to make sure it's a solid build? Any help is much appreciated.

Specs are good. Depends really what you want to do with this pc.
Are you getting a HDD or SSD?

High end gaming in 1080P, not multi monitor or multi card setup. I'm hoping to shove in
a 120GB SSD as a boot drive and maybe to run games off of and a WD caviar black 1TB for general storage perhaps? My current HDD is slow, so I think an upgrade is needed.

Yes, you should buy a SSD for OS and even install few games on it and the rest put it on the HDD. I suggest buying Samsung 830 or 840. I bought a lot of Samsung SSDs for laptops and desktop and I didn't have not even one problem. I can't say the same thing about Corsair or OCZ.
