There isn't a "4GHz" limit to the material used to build these chips. The limitation comes from the operating temperature, once it's over an estimated threshold it will not function correctly at a given frequency and in extreme cases it will be irreparably damaged.

And would you not say this was around 4ghz that this happens during normal operation?

I doublt if nVidia could release a double-chip card based on GF110 like GTX590 or GTX595, which it failed to do on GF100... But it seems that AMD's HD6990 is going its way not long after the HD6970.
So I think 2011 is still a challenge for nVidia.

Well, the problem lies with the cooling solutions, not the chips. When we will accept this fact, we can have today's chips to double their frequency and even more. And that would make sense with 1000$ chips. But a much more expensive cooling solution will not make sense with a 100$ chip.

It's time to innovate the cooler because the CPU is getting boring.
