Does my mother board support dual core

Hello,
wondering if my computer can be switched over to dual core from what it is now. here are the numbers that i could find on the mother board MCP61SM-AM (SF1S S/N) V011120047662653 if it can can you tell me what chip i need to make it work. if it needs another mother board plus chip would be cheaper to buy a comp already with dual core. thanks so much any answer is helpful.
