>Their DNA/RNA/Proteins have a higher GC ratio.

Which does not explain why Pyrococcus growing at >100C has a GC of 
around 35% i.e. predominantly AT rich. Add in the umpteen other AT rich 
hyperthermophiles and your argument falls apart.

There are many other ways to protect your DNA from denaturing, other 
than %GC.
