I think your best upgrade is this:

And I don't think it will be an 'upgrade' to you, because it's not that much better. But it will give you DirectX 11, OpenGL 4.x, HDMI, etc which you may not have. Performance wise, it'll be better, but not that much. You can overclock your card with MSI Afterburner.
