Not really... as I understand it, the most demanding (volume/time) air 
tool is a die grinder (whizzer).

Any new tool should list its air requirements, which can be compared to 
whatever compressor one might be interested in.

Also, at lower pressures, the impact gun just doesn't "hit" quite as hard.

The main reason I mentioned smaller compressors is that with any luck 
they will be quieter, also they are cheaper, and more portable.

Most inexpensive compressors (say, under $800) are single stage, with a 
maximum pressure around 110-130 PSI.  Compare that to any "industrial 
strength" or bigger machine, with a two stage compressor, running over 
200 PSI easily.  And yet the 120 PSI machines still work pretty well for 
the amateur using one tool at a time.  The tank volume, of course, gives 
you longer to run before pressure drops below some arbitrary point 
(unless the pump can keep up with the tool) making life difficult.
