This is going to be a gaming / minor editing build, and my first. I was pretty set on getting SLI 670's but was doing some research and saw the 7970's might be better can any one enlighten me on what's better for my build? Also since my build isn't set in stone if anyone thinks that there is a change i can make to make the build better feel free to make a note on that too.

Couple of things.
You need a cooler for CPU, if you want to overclock. Suggest Coolermaster Hyper 212Evo. In order to fit that, you should get low profile RAM, like Corsair CML.
Cooleermaster PSUs aren't the best. Seasonic, PC Power&Cooling, Corsair, Antec, XFX all good. You don't need 1000w+. If using nVidia GPU, 750w is plenty. If using the Radeon HD7970, it may be worth getting 850w, no more. Check your editing software doesn't prefer one, over the other. If that's not an issue, the Radeon is more powerful, and that is decent one. If going with nVidia, the Gigabyte Windforce, or MSI Power Edition, better than the EVGA.
You should have adequate SATA cables, supplied with mobo.
