Infinite cutoffs with a nonperiodic unit cell are generally advisable for 
running implicit solvent calculations.  They don't parallelize well due to a bug 
that I believe is still being fixed, so you can only run on 1-2 processors in 
implicit solvent.  Performance for large systems actually scales better in 
explicit solvent, especially if you use GPU acceleration.
