I won't claim to be a forcefield expert, but there is 10 years of (hard)
work involved in between ffgmx and ffG43. If that doesn't convince you,
look up the reversible peptide folding papers from Van Gunsterens group
(ETH Zuerich), which show a generated equilibrium ensemble that matches
as close as anyone can tell with experiment, and try to reproduce these 
results with ffgmx. I don't think anyone actually tried that, but I would 
be very surprised if you got equally good results using ffgmx...

As for non-protein related stuff, I don't think much (or anything) has
been changed.
