GRE is *not* supported on 3550/3750s (see the archives for more details).

7200/NPE-G1 should do up to maybe 100-200 Mbit/s, but I'm doubtful whether
it could do 500 Mbit/s.

7600/Sup720 will do "whatever you need", provided you use a different local
address for each "tunnel source" (if you have multiple tunnels on the
same local IP address, the hardware can't do the tunneling, and the CPU 
is much slower).
