Yeah I would say the dual core is the issue there, I'm assuming its a low clocked/older CPU? And as I said Bigbox will run on most things but it does like to have a dedicated GPU in order to use all the bells and whistles, as I said not essential but a IGP is sharing bandwidth across CPU and IGP, with 4GB of ram which is pretty low these days. You could try upping the ram the IGP can use in the bios and test though.
