Engines 0 or 1 are even worse, but I assumed they went end-of-life or
end-of-sale... I'm surprised you recently moved into such hardware. As
others pointed out, you should watch for turning on features(MPLS, ACL
inbound, ACL outbound, uRPF) that this engines either don't support or
have limitations. The lack or limitation of ACL/uRPF features are
dangerous for a network that is connected to a public network like the
Internet or trade association networks, but isn't a killer issue on a
closed network. Lack of MPLS can make you spend more with legacy
solutions, or be a business risk given the market buzz on it.

As for the 7500s, moving 200 Mbps divided among various VIP
controllers is possible, and I think newer VIP cards outperform Engine
0 or 1 GSR cards.

Because trouble doesn't come only from the Internet, customer networks
can also generate bad traffic... internal connections (e.g., between
your routers, either intra-POP or inter-POP) would be more tolerant to
lack of features, but sometimes is more produtive to turn features on
all input interfaces of a single router than all input interfaces of
all routers on the network.

Plugging the FE ports on a switch, perhaps ?
