I don't have any specific numbers for you unfortunately but I can tell you I have used 4500's for IPsec tunnels (3DES and preshared keys) between sites with no problem. This was with T1's interconnecting the sites. The delay was not noticable to the end user or to the applications we ran.
FYI,

Subject: [nsp] C4000/4500/4700 IPSec performance
Is anybody here brave enough to be running IPsec on a 4500/4700 or even a
4000? What kind of performance can we expect from this, especially the 4000?
We have a potential customer who has a pair of "4000" routers (have yet to
verify if it's a 4700, 4500 or even a 4000) who'd like to have an IPSec VPN at
about 512 Kbps. My guess is "no go", but before replacing those boxes, I might
as well verify here. I tried looking for some 3DES performance figures for
those boxes on www.cisco.com but did not find anything obvious. Anybody have a
pointer handy?
