This guy just sounds like an Amd fanboy.
And I'll admit, I'm an AMD/ATi fanboy as well.
But that doesn't change the fact that for AE performance, currently, the Nvidia cards with supported CUDA will definitely help you out more if you ever plan on using the ray tracing engine. if you don't plan on using that feature, well , then it's probably more of an even field, with price to performance ratio being a main concern.
I run a 6970 right now and can honestly say the ray tracing using the CPU instead of GPU is horribly slow. I've bounced around the thought of getting a headless Nvidia card to help with this function, but I probably wont use the feature enough to warrant the card.
Also, I like to play games in my off-time. And for that purpose, I really like Amd/ATI cards more. They offer more power for the price when gaming is in mind. But that doesn't help with production performance.
I don't know how much better the Nvidia card would be vs and/ATI for cinema 4d viewport performance though.
There are also some GPU based renderers for C4D. I'm unsure of benchmark results for those either, but if you aren't expecting to use those, or the raytracing features in AE, I'd say you could probably save a hundred or two by going with Amd/ATI. Haven't checked market prices lately.

I'm about to purchase a custom-build PC and am trying to decide on a graphics card. I want something that works well for AE and Cinema 4D. It seems that both these apps rely primarily on the CPU, and very little on the GPU. All things being equal, I thought I would go with the Nvidia card because it supports the CS6 raytracing. But a guy on a forum is -quite- emphatic that I should get this Radeon card. Can explain to me why he's wrong?
our conversation went as follows: -------------------------------------------- RALPH: Buddy. The 670 is not a good card for workstations. NVidia basically crippled
the cuda performance on the 6xx line to make it better for gaming. Get a
7970 instead, it has way more compute power. ME: I want to go with the Nvidia because Radeon isn't fully supported by
this program I use (After Effects.) Also, someone pointed out to me that
most of my concern should be the wait time on software
rendering, so in my case it's more about the CPU. Anyhow it was helpful
to know about the difference between the GTX 6xx so I'll probably get a
5xx model. RALPH: That's only mostly untrue. From Adobe's system requirements page,
it says only that AMD cards don't support GPU acceleration, an
unnecessary function. Past that, you will get more power out of the 7970
as the CUDA cores are nearly non-existant on the 6xx line, and the
compute power on the 5xx line isn't close to the 7970's. ---------------------------------------------
