My experience differs.  
I have not seen dramatically different performance in practice between coot
running on nvidia and the same program version running on Intel HD4000. 
Yes the OpenGL benchmarks are radically different, but that doesn't seem
to reflect what is acheived by programs of interest.  I notice more of a
difference in Pymol performance, but not such a huge difference as to be a
problem.

I'm running a fanless i7-3517UE (Ivy Bridge).  Totally silent.
