Which of the 2900 series routers would provide at least 2-3 times the performance of a 2811? This router will be used to support connectivity for approximately 65 remote sites that each have a T1 into an MPLS cloud.

Here are a couple of good comparison docs:

Reza's second references would let you compare PPS ratings, so, for example, a 2911's 353 Kpps is about 3x a 2811's 120 Kpps.
Reza's first reference would let you size based on expected usage and WAN bandwidth (its bandwidth to your MPLS cloud).

I would also take the 4331 into consideration instead of the 2900 ISR G2.
