This depends on multiple variables. The 7200 is a single-CPU platform where CPU can go sky-high when using features 
like ACL's, QoS, IPv6 and you name it.. Also, changing from IOS 12.4 to 15 increased
our CPU usage with another 10%+. Stick to the bare minimum of features you really need and you will be fine.
