Technically yes, it will handle it BUT (thats a big but) the 1841 is  
not a distributed router so the main CPU has to do everything.  The  
BGP updates once per minute will crush the router and cause all  
packets to stop.  If you do lose one of your 2 feeds the BGP re- 
convergence when the feed goes away and comes back will crush your  
router for at least a minute (probably 5 minutes for 190k routes),  
all packets will stop.   In a perfect world with a nice stable BGP  
table the router would be fine.  This  is NOT a perfect world.
