Is my build alright?

[antoniomcr]

I just built my PC and was able to save money by using parts from my older PC.
I saved money on the case, 10 GBs of RAM, my hard drives, and optical drive.

So my PC is now: http://pcpartpicker.com/p/YjMvGX

I was able to buy the GTX 970's for $154 each! (Thanks Microcenter/Best Buy)
So I SLI'd and i spent a total of $761.02

However, I'm not sure if you guys think my PSU is good enough.
It's been all running fine for the last few days but is there any long term damage that may occur from using a third teir PSU?
And I'm willing to return my CPU if you guys can recommend anything better while not spending more than $250 on the CPU.
I can still return the PSU and CPU since I bought them in-store at a local Frys.

Basically, did I do okay? Any recommendations or anything I can improve?

its good i recommend changing the processor to a K model where you can over clock it

The CX series PSUs have weak caps, and you'll be putting quite a load on that with the SLI...I won't use CX PSUs at all

I was fearing that. I spent $60 on the Corsair CX but I understand I should not cheap out on the PSU, darn.
Any you would recommend?
