GSR Route Reflector: maximum number of clients?

I have a GSR 12008 that is acting as a route reflector and core router. What is the practical maximum (from an operational standpoint) number of clients it can support? (My Cisco sources tell me that the maximum technically possible is large and does not significantly impact the operation the forwarding of the GSR.) In terms of manageability and simplicity, is it more favourable to have a separate box (e.g. 7206 VXR) handle the route reflector job? Thanks in advance for your thoughts.
