GTX 570 or HD Radeon for video and photo editing?

[murchak]

I am looking for a graphics card that will be primarily used for editing and converting videos and for photo editing in Nikon capture 2.1 or Photoshop CS6. The card should handle a monitor with resolution better than 1900 x 1200.
I may do light gaming in the future.

By searching online, I learned that that Nvidia disabled 3 quarters of their cores for their 6xxx GPUs for video editing applications. I read in these forums about people who bought a GTX 660 or 680 but was slower than their earlier GTX 5xxx video card when it comes to video editing.

So my question is should I buy a GTX 570 (used, budget < $200) or should I look for a AMD card? Any suggestions?
Also, are 7xxx Nvidia cards also optimized for gaming and not for video editing?

As an AMD user, I'll admit nvidia cards are a bit better for gaming, but if you look at comparative benchmarks, AMD GPUs are always significantly better at media applications, better openGL support and a few other things make them a no-brainer for media. This is why I go AMD, better multipurpose cards. Though again, I'll admit nvidiais better for gaming (though AMDs do fine too

Thanks Jaxem.
Can you point out to some sources that show AMD is better for media apps? Also, which AMD card would serve my purpose best (<$200)? In other words, which AMD card is comparable to GTX 570? Thanks

The initial review Toms did of the Radeon HD7870 is pretty good:

http://www.tomshardware.com/reviews/radeon-hd-7870-review-benchmark,3148.html

Take into account, some of the anomalous benchmarks they got have been fixed since in driver updates. You'll see it edges out the 570 in most everything...

...And there's a good one (7870) for $170 after rebate here:

I have a 7870, and it's an amazing card, that $170 is well worth it, the comparable nvidia card would be the GTX 660, which benches a little lower.

UPDATE:

Here's another bench for a video conversion suite that compares it directly with the 570:

Thanks so much Jaxem!
I will try to get that.
