GTX 560 Coming soon!

I've seen this kind of component-cost arguments before.

It's a tricky one, because only GPU-designer directly involved in development can talk about it.
I don't think we should speculate on stuff nobody has a deep and correct understanding about.

Each of us can speculate and would never agree, because only a few knows what's really going on in nVidia or AMD's R&D or fabs.
So lets cut these speculations and talk about how many $ we have to pay for the performance. That's what we all understand, and that's only thing a consumer cares about, actually.
