That's precisely the current situation.  By default, gcc 2.9x will use v2.
With --enable-libstdcxx-v3, gcc will use the v3 library.  Also, -fhonor-std
is turned on by default.  Configure options like --enable-namespaces are
no longer needed.

GCC 3.0 will use v3 by default.

The current compiler and library will probably run better without the
new ABI.  It's still experimental.  GCC 3.0 will use the new ABI, so you
can turn it on if you want to test it or debug it.

I haven't even looked at the new ABI, so I can't answer anything else.
