I recently took two 1721's back to back and tested both 3DES and AES IPSEC.  I 
was getting 1.5-2.0Mb/s using software encryption.  This was tested with two 
linux boxes running iperf.  In some cases the AES seemed like it could push more 
than 3DES.

If software IPSEC is a function of the router CPU you could compare the 1721 to 
the 800 series.
