Having vs. Where clause

[CrystalVis]

will these statements give me the same result if I use them as a criterion to filter data:

Having sum(pmt.amount) > 1000

Where sum(pmt.amount) > 1000

I understand if I use having the processing time will be longer. Any explanation is greatly appreciated.
TIA

Having is used in conjunction with the Group By clause.

Copied this from Help:

WHERE is similar to HAVING. WHERE determines which records are selected. Similarly, once records are grouped with GROUP BY, HAVING determines which records are displayed.
