We have the following setup running and it works great:

7206  IOS 12.2.27

3600  IOS 12.2.27

2 T1s point to point.

CPU utilization on the 7206 peaks at 25% but averages 
around 7%  And the 7206 has a DS3 card in it and a 4
port serial card for the T1s and does a lot of other stuff.

On the 3600 it peaks at 45% but averages 25%

Customer bandwidth peaks at around 1.5Mbt, except at night
when they run their offsite backup where it saturates the
pipe at 3Mbt.
