Can I install a better video card in the PCI express slot of my HP pavilion dv7-1245dx?

I want to add a much better discrete card and disable the integrated card for better gaming performance. Is this possible? Also, what PCI express version is this expansion slot? PCI express v2.0?|||Yes you can install NVidea 8400 PCi graphics card to your pci slot of HP.
