Wow, you're a very cautious consumer! :-)

It may be useful to note that the GTX 480 and 470 are not the most 
recent generation of GPUs from nVidia, there are now the 5xx series. So 
the information in the above link may be outdated. Maybe it still 
applies, but it's worth checking out.

The other thing is if it's only slower for that particular feature, I 
wouldn't call that a severe disadvantage. It all depends on what you'll 
be doing with it. I have a GTX 470 at home, and it's very fast (at least 
compared to my GTX 260 at work, it's much faster).

I haven't directly used ATI cards lately. I have heard they've become 
much better, but still lagging behind nVidia, mostly with respect to 
OpenGL driver stability and performance. Perhaps someone here has used 
recent-generation and comparable cards from both and can better answer - 
that's pretty much the only way you'll be able to get that information.

Hope this helps,
