Be sure to optimize your configuration before you upgrade. 
Depending on what services you have enabled (either by 
default or design), you can squeeze quite a bit from these 
boxes before you need to upgrade with a pretty lean 
configuration - and the NPE-G2 can sit a sweet 2GB of DRAM 
nicely :-).

We've been able to forward some 950Mbps out of an NPE-G2 at 
~72% CPU utilization as a core router, and about 600Mbps at 
the same CPU utilization as an edge router.

With the current bloat of the routing table today, the sheer 
force software routers provide re: RIB/FIB memory for a 
couple-of-hundred Mbps of traffic forwarded is hard to 
ignore.

Cheers,

Mark.
