No, a quad core and a good GPU are required to play the game at high. At low, I'd say the C2D is enough but since its a slower 2.0 GHz processor, it would be a bit too lagging behind. So to answer your question, no you can't run it. Most modern day games requires a good graphics card ( GPU ) to run well.
