If you have a little extra loot, consider an Nvidia GTX 680 instead of the GTX 670. They will both really help your rendering. Also, if you are not using the Adobe Creative Suits (After Effects and Premiere) you will probably be fine with an AMD Radeon 7970.
Let me know what you think!
This wattage of the power supply maybe a bit overkill, but the stuff that I chose is best quality
Uhm, first of all, your link doesn't go to the build you think it does.
Second of all, there is NO reason to get a 680 over a 670 - the 680 is only 5% faster (3% after overclocking of both), and costs $100 more; that's not even close to worth it.
They're (the 670 and the 7970) also both WAY too expensive for a video editing build... especially one that has a Phenom II in it - that's just a waste, and confusing. EDIT: Sorry, I realized that was in the other build you posted - I'll come back and critique more when I know what we're actually talking about.
why? for $1600, you could grab an i7, 16gb + ram, and a mid-range to high end gaming GPU, and a quality PSU that won't crap out on you. which will perform far better for the sake of media editing.
this is the second post i'm seeing from you making recommendation out of the blue, with poor price/performance consideration, that i am slowly assuming you're (poorly) attempting to make these threads more of an intel vs AMD flame war.
